Disgruntled by the manner in which Telkom handles my account

I would like to report Telkom Mobile for the manner my account is being dealt with. Initially i banked with Standard bank and the debit orders were deducted from this account. I called in to inform Telkom that i am no longer banking with Standard bank, yet amounts were still deducted. I paid the account in full on the 27 August 2019 and amount of R1100,69, and even though i informed them of my new bank details, they continue to deduct an amount of R550.35 from Standard Bank , for which i am probably being charged from Telkom charges for unpaid debit fees plus bank charges of R145-00 a time. Prior to this an attempted debit of an amount of R798.99 was made on 02-08-2019 and and on 18 -07-2019, an amount was attempted for R399,50, which is a strange amount and an odd time to attempt deductions for which i am being charged by Telkom, as well as bank charges are being charged. There are a number of deductions taken from Standard bank for which i have been charged and i wish to inform you that this is a completely unfair manner in which this account is being handled. My request is for Telkom to refund all the unpaid charges made by them as well as the bank fees being charged for these debits and that it be returned to my Nedbank account, with immediate effect as i informed them. My Telkom account number is *** for mobile number ***. I cannot accept that this company gets away with this kind of unfair practice any longer. I request that they go back into the history of this account for which i am being charged, while i understand that there were times when they rightfully charged these fees for returned debit orders, i do not believe that they get away with these charges for the rest of the time
