*****ING!!!

I have 3 contracts with telkom and two should've been cancelled around March/April and yet I am still getting debited. I was called by a third party representing telkom to do upgrades and I told them that I didn’t want to upgrade any contracts and they should cancel the contracts when it is paid up and they agreed that it will be done. Its been 3 months and I am still debited. I’ve reversed the debit orders but they continue to debit me and now my service has been suspended. I've been in a telkom store which they told me the contracts cannot be cancelled telephonically but I fail to understand why the person on the phone couldn’t tell me that. A case was logged and I was called back but it seems that the lady that tried to assist me did not understand my problem, she put me on hold for 20 minutes and came back and told me what I already knew. I requested that someone else call me back and there was no return call. I went back to the telkom store when they requested someone to call me back again. Someone called me back and said that they would refer the query to the billings department for assistance. It’s been 3 weeks and I am still waiting for someone to call me back and I was debited again last night. PLEASE ASSIST URGENTLY.
