Power House Energy -- Our Profile Analysis

I had a positive balance according to the recording on the phone but the power was off at the house. I called to report a outage and Oncor confirmed the power was disconnected at power house energy's request. Again I confirmed my positive balance. Obviously at this point I determined that I need to speak to a customer service representative. They are impossible to reach. I called and selected the option on the recording that proceeded to confirm their hours of operation, which I was within, then I was forwarded to their voicemail. The voicemail message said I would receive a call back on the next business day. Being that my power was off I scoured the web trying to find a good contact number for them, even calling the other companies in their group. No one could help or get me in contact with an employee. I left 2 messages that night. The next day around lunch I still had not been able to contact them or had received contact from them. At this point I contacted a different company for power. I continued to leave messages to try to find out what happened and how I will receive my credit for the positive balance I left in the account when the new company took over. At this point I've left 14 urgent messages over 5 days with no response. I can't imagine a way to have worse customer service and I still have no idea why they cut off my power.
