Pathetic service from Telkom

I have a contract with telkom, earlier this year a ********** number was added to my account. I then reported it to Telkom and they gave me formal notification that their investigation found the account to be ***** and they will cancel it,this was on the 21st of July 2017. Almost two months later , I am stuck with a bill that is almost 6 times my normal monthly bill. When I call the call centre , they give me the run around and it's u fair since I never give them a run around when they need their money.
