Charging me R200 for what? Incompetence? And handing me over for what? 1 missed payment that wasnt even my fault!

Last month by no fault of Telkom my husbands salary came in on the 1st. They tried to collect on the 31st but it was unsuccessful so they didnt disconnect our services but handed us over for 1 missed payment. They sent my husband a new bill where they would collect the amount of R936 at the end of February. Because my husband pays weekly, they put a naedo debit of R468 two weeks ago, and another this week Friday. We didnt mind because then it would mean no debit order month end. To our sorrows the payments have not been allocated and the account shows in arrears. We called the call centre, sent through our bank statements it hasnt been fixed and still reflects in arrears. I called this morning and advised that i will be placing a stop order on that debit because its going to mess up my account and my other debit orders. Only to be told not to do it because they are going to charge me R200 for the unpaid debit order. R200 for what? Because the account is paid.
