Trying to cancel service since June 2014

Service no: ***.<br> I have been trying to cancel this service for last 7 months. Numerous calls made to find out about coverage to find out in June that there is no cover in Parys for this service. I requested the cancellation by sending in a letter, as a call centre agent told me I should do. I then waited for the cancellation to happen,a number of months went past and the debit order continued to go off my account. in October I cancelled the debit order at the bank, i then received numerous calls because i wasn't paying ( for a service i had requested to be cancelled. i repeatedly told the staff that i had requested a cancellation, i was told by the same staff they would escalate it to cancellations, I never heard anything back. i called again to speak to a lady that sent me a cancellation form (an 8ta form) I completed this and sent it back with another letter. Still nothing. I have now been handed over to a collection agency. i have on Friday emailed my documents again and on Tuesday drove to Potch to Telkom to find out what is happening. i am told i filled in the wrong form and a new one was completed and faxed. Now it will be cancelled eff 29/2. This is unacceptable!
