Bad service and billing issues

I recently took out two contracts, one for my wife and one for myself. Prior to the sale, everything was wonderful. After the sale, problems started being encountered. First of all, I could not get my wife to keep her old number. 3 weeks later we were still battling to do a simple number change. Telkom then suggested we cancel the contract, change the number to my name then reactivate the contract again. Low and behold, this worked and my wife finally had her old number back. Next problem now arose, Telkom now billed me a cancellation for the contract yet the contract isn't cancelled and still in fact active and both under my name. This should never be the case as it was their suggestion to get the number on the contract and working.

Now my solution to the 3 weeks issues I am having with Telkom is this. Should this run off my account when my account gets debited, I will cancel both these contracts. Today is the 13th, Telkom you have until before the 25th to sort out your incompetence.
