forced into debt and *****

I went to autopage and requested a cancellation fee and I was give the amount and told to pay within seven days. On the eighth I paid and called on to cancel the contract it was confirmed that it was cancelled. On the 17th I received an invoice to pay for the next month, I called the customer service and I was told it was reversed as I can not afford. I don't understand that and I have done what was requested. I cancelled it so that I can be debt free not to be de*****ed *******. The call center is no help they keep telling me it's obvious autopage will make it sure I paid more than what the contract should have been if I waited until February to cancel it. But according to the NCR that is *******.
