My account with Telkom was in arrears, I didn’t update new bank account details

My account with Telkom was in arrears, I didn’t update new bank account details. Arrears were paid, services were reconnected, however my account is still with lawyers. Despite date given to debit I am told the collections system does collections randomly. Debit went off on the 25th instead of the 15th, account has been soflocked again as the payment is still not reflecting from their side which is a period of 7 to 10 working days, I don’t get an explanation why account is still with lawyers who debits at their own time that delays payment reflection at their end. Every month i am facing account being suspended because of their incompetence while i have paid on time. It is not fair
