Telkom billing is up the pole

Got to be honest I have had nothing got good experience with the telkom store and telkom sales people liberty mall telkom have been fantastic and always willing to help. But my problem with telkom is there billing and accounts dept they are useless and ***********. End of Nov 22 we discovered ********** activity on our bank account. We approached telkom in the first couple of days of December 22 and explained the problem and updated the banking details. I went and paid the November invoice at pick and pay. At the end of December telkom in all their wisdom tried to take the debit order off the old account found no funds and disconnected my services. They then tell me it's my problem and they will take a double payment at the end of January 23 and charge an additional R230 for non payment. ***. Crazy thing is it's no point even griping on this platform as telkom doesn't respond to any complaints.
