Still overcharging. No cusomer support

SO... I lodged a customer complaint about MTN Datalive PSD charge on a contract I DO NOT USE. Its off most of the time in my bedstand. My previous store visits, phone calls, hello peter complaints have delivered no result. Since September of last year I have been charged between R147 and R250 per month in addition to my contract charges.<br> <br> There is no number to phone to speak to someone. I DEMAND A REFUND or credit to my account to the amount of R1647.93 which is the amount billed. <br> <br> Their previous response was merely sorry sir, this is due to a service activated on your bill. THE FACT IS I DIDDNT ACTIVATE THE SERVICE!!! I WILL KEEP HAMMERING ON SOCIAL MEDIA AND WHERE EVER TILL I GET MY REFUND!<br> <br> THIS IS THIEVERY!!!
