"Rolling Charges" torment

Rolling Charge are Cramming by At&t. Here are the educations, I expereinced currently. My July end billing date is the 5th. My new august bill starts July 6th. every month 5/6th are billing migrations dates. So, on the 6th of july, [AUGUST] bill showed [unpaid[ amount of $39.85.

also, this was the [end] of my first year promotional offer. No problem-I thought. I [paid] the $39.85 with my July/August bill. The [$9.00] late fee was honored for removal, so I was told. The [new] promotion for more speed, ( which I did not need) was forced on me to buy, as the coustomer service agent, [inferred], I could not keep my current speed and protional pricing of $39.95.

Reluctantily, I agreed to the [new] promotional 18mbps at $56.00 per month with a $11.20 change discount. making my [new] 12 month deal, $44.80 per month. I learned that even if a small balance of $0.17 is not paid before a specific due date, [we will incurr] a "ROLLING LATE FEE OF $9.00].

By the time I paid [double July/August bill in August 6th, more "rolling fee's of $9.00 were added/deleted then added again! I even went into pay the $1.00 more before the due date just to test this theory. I was correct, Not only did AT&T not change the balance to $0.00, or , make corrections in the data base at the local store I frequent, they offer's some credit's, and STILL posted a charge due of $18.00 ! 9 plus 9 is 18. THIS IS CRAMMING

When I clearly paid both the July bill and the August bill in August with the $80.00 payment. With the rolling Fee's, October/Novemeber are fonky too! 

I expect a fresh start of a bill that reads: PAID IN FULL. $0.00 and the upcoming charges for your current promotion are $44.80, minus the $11.20 discount..for a 18mbps.

That's what I expect from my carrier-respect not double talk and twisted hot plate responses from the chat room.
