Who F told you to debit my account!?

I've been with CellC almost since they existed and for over 5 years I have been paying them via EFT, ever since I opened up another data SIM, I have been debited.

I pay for all my accounts including my wife's in full based on the statements provided and still I was debited R322 odd.

I called last month and demanded my account be removed and was told that debit order is mandatory , firstly this was not mentioned to me when I took out the new SIM through Cell C direct, and secondly I did NOT give you permission to debit my account.

Urgently refund that amount, and I want a formal apology letter for pathetic service I've been getting every other month, including your network signal being slow every other day (Yes! it was logged)
