Directv issues

Where to start, so about 10 months ago I was checking on canceling my service so I spoke to a cs rep with directv and they told me the charges. After hearing them I told the cs rep that I would have to think about it and call them back. The next day I wake up and no tv, I called the directv team and they told my service was canceled and I needed to return my equipment, a few days later I received a return box. After receiving the box I decided that if they didn’t want my business that I would just send them their boxes back. After several calls I finally got a supervisor on the phone that told me a woman called in and canceled my service. I have ask for the recording more than 6 times, but no luck with that. I talk to someone today that told me that I would have to have gave my info to someone that called and canceled for me after they authenticated they security question. I ask him what that consisted of and he told me the PIN number was required for anyone to get into the account. I ask him did he ask me my PIN number when we started and he was quite. We had been speaking about several private account items and he knew he had not ask me. I ask for his supervisor and he told me to hold on.  After I have been on the phone for over an hour with directv, he told me his supervisor was busy but would make sure he would call me back today before he went home. Well it’s the end of the day and I haven’t received a call back. I need help resolving this issue. Does anyone have any insight on what the next steps would be that I need to do?
