I Need to Speak to Supervisor - DirecTV

I have spent three days trying to straighten out the billing on my account. Some of the problems I was finally able to settle with an English speaking representative yesterday but I still have some questions. Most of all, I want to know how this mess happened. I asked to speak to a supervisor three days ago and was told that one would contact me. No word yet.

This question, "I Need to Speak to Supervisor," is about DirecTV channels, programming, equipment, and sports.
