I am trying to find out how to get in touch with a manger or supervisor for customer support. I have been waiting 5 months for them to correct a promo credit on my account. I have spend over 30 hours on the phone, chat, and text to correct this issue. I have been told 7 times that the issue is resolved and would reflect on my next bill. The issue started when my original promo credit amount for a trade in was not able to be accepted due to a system error. I was told it would be corrected as soon as they received our trade in phones. I have screen shots and recordings of them staring over and over that all of the notes on my account reflect this as well. I have been told that a supervisor is correcting it immediately. They have corrected two of the four lines. I am so frustrated with this situation. Does anyone have advice on how to actually speak to a supervisor or manager since I am told they aren't available every time I ask? This is the worst customer service I have ever experienced. Please help!
