Not cancelling my contract

Hi there, I have had three contracts with Autopage in East London Devereux Avenue. All my contracts were cancelled in October 2015. Every month since then an amount has been debited to my account even though the contracts were cancelled. I have repeatably contacted them to request assistance in firstly stopping the debits and second to get a refund which has amounted up to R1,150.00. I emailed them again on the 25 February 2016 asking for feedback as I did not want to be debited again. They responded to my email stating no debit was loaded on for the month of February. No news on the refund. On the 01 March another R284.49 was debited to my account. I went to Autopage only to find that the premises in Vincent was now closed. Not once in all the time I was in contact with them did they say they were closing. I then tried to phone the call centre *** and after holding for 10 minutes the call was answered by Zanele. I explained the whole problem and I could tell she did not know how to help me. She answered OK and promptly put the phone down on me. I am presently holding again 21 minutes and counting. Shocking service, I am very disappointed.
