When my bill with AT&T went up by 80.00 dollars, I decided to cancel. I called the number on my billing statement and was directed to a representative who advised me that my contract had expired and that I would be charged the new amount for the current month. If I wanted to cancel the service I should do so by the 10 th of the next month, to avoid being charged for yet another month. I did as they suggested and paid the increase for the current month. When I called to cancel I was told that they would honor my request and cancel my service. I then had a new service from another provider installed. Two weeks later I received a bill from DirectTV for 113.00 dollars. I called and said that I cancelled my service on the 10 th of the month, as I had been instructed to do by their representative. The person with whom I was speaking told me I would have had to cancel by the 8th of the month to avoid being charged . Since they do not prorate, They said I owed for the entire month even though I had service with and had paid the new provider .
