contract cancelled bt still deduct

I have called in April to cancell my autopage contract, they have said that the last installment will be in the month of May, now I call in June to find out if everything is cancelled and this ***** has a bad attitude telling me that the last payment is in June bcoz of some arrears that they work on. I have never been in arrears and they deduct every month more than the installment of R358. I payed R358 for one monthnin the 24 month contract, every month thereafter has been over R400, dont open accounts at Autopage lets try and shut this company down , I feel they like ********** honestly.<br> <br>
