Bad service

I, Andrew Martin van Heerden cancelled my Data Stick (2GB for R149 per month) a while ago. According to Cell C it was not cancelled and they are still deducting funds from my account. If I do reverse the amount then they just withdraw again and it's costing me all the bank charges.<br> <br> I have spoken to a man called Hammond with reference nr : *** and it is still not cancelled. Documentation was also send from Wonderpark Cell C in Pretoria North by a consultant named Suzen.
