Telkom mobile refusing to cancel my contract after it has expired.

What does one need to do to cancel a contract? My contract has run its course and I have given Telkom mobile 3 mail notifications with the required documents to cancel, and yet nothing has been done. Now, we all know that if I cancel the debit order, they can and probably will list you for a bill, that one has requested to cancel.

I spoke to John and he promised me it would be cancelled. This took place early February. I then called today and I was told a manager/team leader will call me back. This happened today at 2 pm. You guess it I am still waiting.

I will not recommend Telkom mobile to any one.

Cancelation of contract x2 : Smart internet 1 GB - Account ********** 19

Absolutely pathetic.
