Telkom Mobile failing to cancel contract

Evening<br> <br> Mid Oct 2015 I phoned customer service to find out the cancellation procedure. I was told that I had to go into a store to cancel the contract and that as per the agreement I have to give 30 days' notice for the contract to be cancelled. At the end of Oct I went to a store to cancel just to be told that they do not do cancellations in store, but that I can fill in a form which they will send away on my behalf. This after I had to wait for almost 2 hours in the store. I decided to fill in the forms and they informed me that someone will contact me to confirm the cancellation. It was at this time that I was informed that it would take 3 weeks to process.<br> <br> On 20 Nov 2015 when I have heard nothing I contacted customer service again to hear what is going on as I have not received any feedback. They informed me that no cancellation have been processed. Extremely frustrated I filled in the form again and send it via email to have it on record. To date I have not received any feedback. Telkom have debited my account at the end of Dec 2015 and I was send another Invoice for Jan 2016?<br> <br> I want this resolved without delay as Telkom is taking money from my account without consent.
