Cell C theft out of my bank account

My wife's Cell contract expired on 11 September. We cancelled the contract well in advance. We were supposed to receive a pro rata bill end of September. We have now had 3 debit orders since then for the full amount of R 239.00. Each time we reverse the debit order at a cost of R 20, the full amount is just deducted again. I got an assurance from the customer service consultant on 16 October( Ref ***) that another debit for the full amount will not occur again and low and behold the 3 d one just went off again this morning. <br> <br> I want a resolution to this ongoing saga. I also insist on a refund for all the debit order reversals I had to request. My personal Cell C cell phone contract is soon up for renewal. I this matter is not resolved to my satisfaction I will simply chose another service provider and never deal with Cell C again.<br> <br> I am providing my Wife's ID and cell number below.
