Telkom Business Mobile employee failure

I have a contract with Telkom Business Mobile. My account has been suspended because one of their staff has failed to load or reactivate my debit order and they did not debit my account on 5 February and I have made a manual payment but I am told to wait 48 hours due. Why am I on the receiving end of Telkom staff mistake? I have been promised a call back by Seipati Sekaba a call center agent and her manager after I sent proof of payment and I have not been contacted nor reconnected. No call received, no reconnection only people that don't want to take responsibility.
