Unable to resolve customer complaints

I am highly disappointed with telkom. They are quick to deduct money,yet they are not able to resolve issues. Since July 2024 telkom has been billing me incorrectly. The call centre agent told me that telkom is aware of this issue and im not the only customer facing this issue. From July 2024 a total.amount of R475 as been overcharged. I got told to be patient. Every month the amount is higher. If you reverse the debit order telkom charges 200 rand extra fee on your bill. Seriously when my contracts are done. I'll also be done with telkom.
