********** debits

My contract with CELL C was cancelled on the 15th of May 2017. I was advised by the Cresta cell c branch to pay a cancellation fee of R749.58 into cell c account at Nedbank. So i did the cash deposit and went back with the proof of deposit to the Cell C branch and the lady there advised me that all will be sorted out at the cell c head office. She did not ask for the cash deposit slip to fax to head office. So i took her advice thinking that my contract was cancelled and fees due from my side was all settled. On the 31st May. Cell c debits my bank acc for R749.58 which i had to call Fnb to reverse immediately that morning . Again on the 14 June CELL C debitted from my account , this time 2 different amounts but also amounted to R749.58 which was the cancellation fees which i had already paid. I called the call centre at CELL C and they confirmed that R749.58 was reflecting on their system as paid so i thought great all sorted. I reversed the two separate deduction once again. There were extra bank charges incurring on my fnb account because of the debits and reversals. Then on the 30 September i receive another notification that R283.29 was debbitted from my Fnb account, Cell C using a different reference number this time and different amount therefore thecdebit went through. So when i stopped the debit orders with my bank , Cell C **********ly used a different reference number and changed amounts to debit my account this time R283.29. When i call the cell c call centre was advised there was no information on my cell number as my contract is no longer with Cell C. This just added to more frustration! I would like Cell C to reimberse all the unnecessary bank charges incurred to my bank account and to make sure that my account is NOT debbitted again!!
