MTN BAD SERVICE

I phoned Mtn call centre in August 2018, as I DID NOT want to renew my data contract with them. I was informed that a new contract had been taken out on my name without my consent. I was informed by the call centre consultant to go to my nearest police station to do an affidavit and hand it in at my nearest Mtn store. I immediately went and made an affidavit and handed it in at Mtn Uitenhage, Eastern Cape and the shop assistant informed me they will contact me to come and collect the necessary documentation and recording. The shop assistant nor anyone at the call centre has contacted me regarding this matter. The call centre consultants I have contacted have refused to inform me what contract was taken out on my name and where it was delivered. After numerous calls and visits to the Mtn store, this matter has still not been resolved. The debt order of R450 went off twice from my account. After the first debt order I went to the bank and they advised me to reverse the payment. I have not been receiving any data from my previous contract as Mtn has stopped supplying me with data. The call centre consultants refused to let me speak to there senior or supply me with head office contact details, as they say they are still investigating the matter. They say I am only able to talk to the call centre. This has been going on for almost two month and yet no solution.
