What to do if Cell C just debit your bank account numerous times every month and incorrectly????

<p>Cell C just debit my bank account 3x times at month end. Not any amounts on my contracts - one they cannot tell me anything about. Nobody knows anything or can do anything about it?? Would be really great if somebody could call me that knows what they are doing and can actually do something not just give me another number. I am collecting incident numbers: ***,***,*** to name a few. If I do not get a satisfactory answer I am going to get the bank to reverse ALL the debit orders.</p>
