Mtn
Billing excess

I have requested mtn to stop over billing me because I don't know the company that they say is billing me through them, the consultant promised to cancel this billings however I still get extra charges.i have been billed more than R300 already that I know nothing of. I m so tired and wish my contract with mtn could just come to an end soon. I have been with other subscribers and have never experienced such a bad service, how I regret having a contract with mtn. My number being billed is 071 887 9099
