Paid FULL Settlement amount yet still being Billed

I took out a 2 year contract with autopage where i got an ipad and a sim, both sim an ipad was ****** so I paid my full settlement amount in January 2015 and requested that my contract be canceled i have proof of the payment made.<br> <br> No one at accounts logged the account as cancelled and the money was used to pay for my contract in advance, so from September 2015 i was Billed again as the contract just kept on rolling,. iv tried contacting Autopage all they say is we will come back to you and yet my money is still being deducted from my account.<br> <br> Pathetic service as i now need to go to my bank and reverse the debit order every time.<br> <br>
