Failure/refusal to cancel contracts

My contracts have expired, and I have been trying to cancel from 3 November 2015. Despite the numerous calls, emails, and completion of cancelation document, I am still being billed at 6 times my contract rates. My emails are read and never attended to.<br> I have requested to speak to managers, however, they are never available. I requested the cancellation of my debit order, but this request was refused. Now I find myself stuck with a service provider who prides themselves in taking our money and neglect to address the problems we experience. Telkom's turnaround time is 20 working days to attend to emails/cases,etc. I am still to receive any form of contact from them. I strongly advise people not to fall into their trap of attracting customers with great deals.
