Direct TV Over charged account Waldport Or, Oregon

I was paying $77.99 a month for about a dozen channels that we watched. Decided to cut the cord since I was on month to month. Called an agent on Apr 24th to cancel services. He said a letter would be sent out within 7 days, which I never received. Was paid up thru April and told them to cut service on the 30th. They disconnected me on Apr 27th, which I didn't care. Called back on the 30th to see if they would send information on returning equipment. To make a long story short (pun) the agent offered me a great deal for a one year contract. I agreed. They must be hurting to offer deals like I got huh? Yeah right! Tried logging into account, but so called agent screwed up e-mail address. Took me 2 days on chat and phone to get it fixed. Logged in and the bill due said $82.14 even after all the deductions for the new deal. Called Rep and she said account was never closed. How convenient huh? They carried over the previous rate and said that was due on the new billing. The Rep said there was nothing she could do about bill and she is in billing. Will pursue this but nothing will come of it.
