They applied someone else's payment to my account and my payment to someone else's account. Basically, only part of my bill was paid even though I paid the full amount. Hours and hours on the phone talking to different agents, managers, etc. I've sent proof of payment several times but no resolution. They're threatening to disconnect my service if I don't pay the outstanding balance which I don't even owe. They're adding late fees on the outstanding balance too. I'm a business and am switching to directv and AT&T because of this. What a pain and what a nightmare.
