Direct TV AT&T Without notice, they back dated my billing date from April 9 to March 30. Illinois - National

When I received my bill for Mar-April, my billing date that should have been April 9, was moved back to March 30th with no notice. I repeatedly contacted them asking them what was going on, and I was not going to make two payments in the same month. I was told repeatedly that this was fixed, and it was not. I finally filed a BBB report. Meanwhile, I payed my bill every momth by the ninth. The bills became increasingly hard to understand. Finally in June someone called from President's office saying it was resolved, but no one knew why it was changed,. Whatever. I was waiting to receive my July bill to see it it was. My due date moved to the 19 of July, which whatever is fine, it is supposed to be the 9th.. However; It said I owed 171.00 instead of 107.00. I called regular customer service - they supposedly had history. When it was looked over, they basically told me that the 64.28 was because I did not pay for one month, which was not true, and my BBB case was thrown out and my billing date had changed due to some Illinois law, which I had never heard anything about - but the Rep did not elaborate. I argued that I do not owe anything past due..went on and on. Finally, I hung up, and scheduled "past due' payments. Done with this company. As soon as my contract is out, going with Dish or some other company.. They lie and tell a different story each time you call. DONE DONE DONE
