MTN debiting me

To whom it may concern<br> <br> I placed a complaint with hello peter, got a call from MTN and they said they would sort out my problem since I'm not with MTN yet they are STILL debiting me every month for a service that I do not have. I switched over from MTN last year already, why are they still debiting me??? <br> I reversed the last payment and got an sms from them about my account not being paid.. I don't understand cause I cancelled my contract with MTN last year SEPTEMBER? WHY MTN? WHY?<br> <br> Please can you fix this soon because I have to call standard bank every month to tell them to reverse the money you are debiting me. I am with Vodacom and have been since September last year. Please guys, this is becoming a bit much.
