Customer service

I’ve spoken to 12 people today. 12 people!!!!  trying to get help with my bill. I’m still on hold waiting for the 13th person. I got rid of the tv service back in May and was told that once I turned in my equipment that my bill would be adjusted. Well, my bill hasn’t been adjusted and my service has been suspended because my bill hasn’t been adjusted, so it’s looking like I own $900. I was told this by 3 different people back in May. If the calls are recorded please listen to them about the adjustment. I’ve been on the phone since 5pm and it 7:30pm now. I’m currently still on hold waiting to speak with the 13th person. Ridiculous!  People are hanging up or just transferring me all over the place because they don’t want to deal with the issue I’m having. It’s sad! I should not have been on this phone for 2 hours with 12 different people. This is very poor customer service. I even spoke to a supervisor, he told me he would help me, but then transferred me back to the same department that transferred me to him. Unacceptable!
