Poor customer service

In October my account was debited yet Telkom was unable to allocate my payment. My account was suspended and handed over to your collection department inspite of the amount being paid. This month once again I have a debit order issue. I have been a customer for over 2 years now and never had a problem with my debit order. It has always gone off my account. This month it ought to have gone off by the 25th. I received an sms indicating that my payment has not been received. I looked at my bank statement and low and behold, my debit order did not go off. I have not cancelled my debit order so why did telkom not debit my account ? I have tried tirelessly to make contact. I messaged your face book profile and I tried contacting your call centre but it has been futile. This is now my last resort. Can someone please contact me urgently to discuss this matter. I do not even have banking details for Telkom even if i want to make payment by eft. I would hate to have my account suspended once again. In fact I am actually looking at cancelling my contract with Telkom. This is extremely poor service and it is happening constantly now.
