Very Reasonable

The company I was with (Reliant) seemed to be a bit high and was going up, I looked at a few different companies and went with Constellation, I'm liking the prices so far, Nothing outrageous and fits my wallet.

Pricing for this electric company have been reasonable. During the winter storm NO price gouging, as a matter of fact my bill was lower than the previous month. Guess the truth will be in my next months bill. I will give an update.

Read the EFL fine print

Order was easy. Account transfer no problem. First bill was higher than EFL facts said it was going to be. The distribution charge from the electric distributor was about $10 higher than what EFL said. Called Constellation and asked why, they said distribution charges had gone. They went up the first month after I switched. False advertising by Constellation.

What can I say they bill me monthly for electricity

I had no issues with billing which is usually the cause to hate them. I had an issue with signing up since I had my credit locked. I wish they would tell online you who they use to check your credit so people can unfreeze or unlock their credit before hand. Like all electric company's they get you in with a good rate then charge a lot more to renew, but all companies do that. All that being said it was a good experience with them and I wish I could stay with them but on to the next with a better rate.

Constellation Energy

Billing is easy to read and understand, when it came time to renew I called and the customer service line was answered quickly, they spent time answering all of my questions to help me decide on the best plan for my needs. Pricing seems comparable to my last electric company before they were bought by Direct Energy who I do not recommend.

"Authorized Representative" Option

I enroll our home, also two other accounts (older ladies, one is 93 and the other is 100) - in the application process, there is a place to include an "Authorized Representative" and I properly entered my name as an authorized representative - however, when calling customer service, I am NOT included as an authorized user on any of them - not possible to put the older ladies on the phone to authorize - including such toption is a good idea, but disregarding the "authorized user" is unforgiveable

Fine at first

We were very happy with the price. very affordable and good service. but then it came time for renewal and I missed my time. the price jumped and now I have a ridiculous bill that I cant pay. I have been very unsuccessful at changing the plan to a lower rate. the website is useless for choosing a new plan.

Misleading Customer Service Agent

Let me preface this by mentioning my experience in 2020 when renewing my service. The customer service agent was excellent, walking me through prices and selecting a plan that best fit my needs based on my usage going back to 2018.

When I contacted customer service to renew my contract in 2021 I requested a rate that works for me based on my usage, and was quoted 10.2 cents based on 1000 kwh. My usage usually hovers between 400 - 700 kwh, and I should have checked with him what the 500 kwh rate was... but going on my previous experience I trusted that it shouldn't be significantly higher than 10.2 cents.

It was 14.2 cents... a far cry from my previous rate of 11.3 cents. Did the customer service agent lie? No.

Did he clarify with me that his 10.2 c/kwh rate is nowhere close to the actual rate that I'd be paying according to my historical usage? No. I felt it was a deceitful tactic to say the least.

Moral of the story, don't make my mistake. Double check the EFL *before* you agree to renew.

Wow real jerks

We had constellation for two years. Paid on time, never had to actually talk to anyone and Oncor did all the work if there was a power outage. So we switched providers for a better deal. My wife accidentally forgot to pay the bill the 2nd to last month. I got no phone calls, no emails, zero notification until a pink slip showed up saying we had 10 days to pay or they're cutting off service - WOW. So I immediately paid the past due amount only to have a notification from their collections department show up two days later. Dude - I have a perfect payment history, its a flipping pandemic, you made zero attempt to contact me - this was such a sleazy move. I am so, so, so thankful we made the choice to leave. So they'll be great, just don't make any mistakes or you'll be dealing with their nonsense. Seriously - one missed payment with a perfect two year history. If I were constellation I would have called just to check on me to be sure everything was okay since it is so out of character. I cannot stress enough that I would not recommend constellation to anyone.

Was suckered into a 3 year contract

I was told the AEP delivery charges were included in my 0.9 cents plan. That's literally the only reason I agreed. I will be calling and speak to a supervisor to listen to the original sales call to dispute my contract. It's not right to lie to a customer to make a sale and lock them into a 3 year contract. This is dishonest and I won't stand for it.

Nightmare

I transferred to constellation 2 week before service. I got an email saying I was confirmed and ready other service cut the electricity off but nothing was turned for over 8 hrs later. They lost my application..i had to go thru the entire process again. Just got my bill and without the bill credit it would be the highest in the last 5 yrs. Understand I put in a new unit 2 years ago. Not sure i will wait 11 months. I may pay the early penalty.

They Failed to Provide Service

I confirmed my contract start date in early July to match up with the end of my previous contract. I received multiple notices confirming the contract. After a month without a bill, I called, was told there was a database error and that it was fixed. A month later nothing had changed. I called in to be told my account was not active despite never being given notice of a delay or cancellation in my order. The service had defaulted to that of the apartment complex with disconnection fees because Constellation failed to provide service as agreed. I never received an explanation as to how this happen and once I was actually told they weren't providing service, I closed out the account to seek other service.

The price, if they actually provided service, was decent.

Bait and switch or outright lye when you call, by far the worst CS ever

Find another company. I can not record this enough.

Lets start at the plan. I called them to confirm and asked questions, I was told they charge buy the KWH, whatever I use, I get charged for, they confirmed the rate, so signed up as my previous contract was ending and they offered nothing at market rates. Set up to start, on the last day of my previous plan and the day my meter sends in its readings.

First bill come n a few days later for 150 bucks. I call them, they try to tell me my plan has a min charge of 159, Nope, then that I am prepaying for future usage, nope, so after 4 people finally get someone with average intelligence who can see it is wrong at my bill is correct.

After he first full month I get another bill. Again, charging incorrectly, charging me for almost twice my usage. Again I call, again chuck and jive. After multiple people finally get Simeon who can see something is off, but can not fix it. Get another and he stats telling me I clearly am stupid and can not understand math (side not, I hold a BS in mathameyics and a BS and MS in engineering, AND a MBA in finance, so clearly I have an ok understanding of math. After I get a claimed supervisor I get it partly corrected, atleast it is within 20 bucks of what it should be, bit I am done, 50 bucks to cxl worth every penny.
It 8 days into my moth and I start with another company. I get a bill for 748.24 cents. For 8 days and a 50 dollar fee.

Again, speak to several people, finally get s energy who comes up with 128 bucks, more than my average monthly bill the last 2 years.

I ask of an accounting, and a corrected bill.

I never got it, called again.

Now. Get a late notice. Call again, they refuse to send an invoice or tell me where they get the Balance due.

Still waiting.

Got another letter, but still no accounting. I pod it just t be done with this.

I highly recommend you find another company.

Lack if transparency

Called July 19 about 3PM with the intention of leaving GEXA. Plans and most reviews were pretty good. I asked the agent three very simple questions. Took 20 minutes to extract those answers. The questions were these. What is the price per kwh at 1000, 2000, and 3000. Was told the numbers would vary from the quoted rates. So I asked the questions another way. What is the highest kwh rate I would pay between 1000 and 2000, 2000 and 3000, and 3000 and 4000? Finally got answers after just flat insisting on them. Final question was: Will you send me those quotes in writing. Agent stated they would only send the 1000 kwh quote. Spoke to supervisor Daniel Garza. Again, went around the world to finally get the quotes I needed. However, would not agree to put the maximum kwh price in writing. Really disappointed in the lack of transparency on these calls. Would have signed up in 10 minutes if getting answers were not the equivalent of pulling a wisdom tooth whose roots were wrapped around the jawbone. What a shame. Was prepared to become a Constellation customer. Guess I should have tempered my expectations before I called. Really sad.

Horrible Customer Service

Service not turned on as requested and agreed when I signed up for service so power was shut off when contractors trying to work. Customer service phone number required 20 minutes before I reached someone. Customer service claimed it was Oncor's fault. Oncor confirmed Constellation never submitted request. After 2 more hours, learned Constellation is a manual process and they didn't submit request. My contractors and I lost 4 hours of our day troubleshooting ourselves and waiting for power.

Long time customer

Have been with them for a couple years. Their prices are not great and the sneak in extra charges when setting you up initially. They did fix this for me, but only because I caught them and took the time to contact them. Then I had certain things removed from my account that they claimed would still be in effect and I did not find this out until it was needed. Shady.
