The disappointing service

My bank account was debited without any notification from Telkom today. The debit order usually goes off the last day of the month.After calling the call centre I was told that it was an error on there side. The service I received was disappointing as I was told they could only help me once the payment reflects on there side.My account has been debited for two months because there system has not been updated after I manually paid the outstanding amount due to Telkom for last months account . Even after the payment reflected on there system I still had to wait for 4 days for my phone to be back in use. The service from the call centre was completely unprofessional as the agent told me the error will only be fixed next month! I need this payment to be reversed and my debit order amount to be corrected ASAP as Telkom has absolutely no right to deduct money from my account especially without notification!
