Incorrect billing by Telkom

I have been involved in a dispute with Telkom since September 2018 as a result of a billing issue. after 5 months, Telkom eventually processed credits on my account to reverse the incorrect charges. However, on the 8th of March i received an invoice from Telkom which once again reflected the incorrect monthly charge.

In September 2018 i migrated from ADSL to a fiber line with Vumatel. I selected Telkom as my ISP as I had an existing relationship with them as they were previously my ADSL provider. However, the package I signed up for was the VTH 20/2mbps, at a total cost of R807.00, however, since inception, I have been billed R1400 per month.

After months of back and forth I was finally told by an agent this morning that Telkom is in fact incorrectly billing me for an ADSL package (Home uncapped 20MBPS) (R1007.00 per month) as well as a charge of R695.00 per month for the VTH 20/2MBPS package. They have processed a discount of R366.00 on the ADSL portion of the invoice.

I was on hold for in excess of 3 hours trying to rectify this issue this morning to no avail. Nobody at telkom has been able to offer any insights into why I am being billed for an ADSL package which shows as "cancelled" on their system. They also told me that they "are unable to log a dispute on the Home Uncapped portion as a result of the discount which has been app**** to the account"

I am at a complete loss for words and nobody at Telkom has been able to assist.

PLEASE HELP!!!!
