Worst customer service and worst toll free service

Worst customer service and worst toll free service. we had a ADSL connection earlier and upgraded to fibre through vumatel fibre. At the time of process we submitted documents for cancelling of ADSL and landline. What happened is they upgraded the connection and telkom didn't disconnected the ADSL line and landline. We explained this issue by going to Rosebank Telkom office and through toll free numbers (Check the logs and CC footages) every time they say you didn't initiated and ask us to submit a request now. This happened for the last 10- 12 times and we are doing so. But they are not willing to cancel because they can charge the customer for both fibre and adsl services. This was happening to me from last 7 months. Is this a kind of joke to Telkom by fooling there customers and rob the money?. Finally last month someone reacted well from contact center and cancelled the landline and ADSL, however he told us like when the next invoice is generated call us again and update us that ADSL has been cancelled, so that Telkom can revise the invoice and send us the updated invoice for payment. Today we called the customer service and they started the same story again saying that you need to pay the total amount and from net month you bill getting invoice for only fiber. My actual plan is 899 and from November I am paying 1500 - 1600 every month. Telkom is responsible for crediting my amount back which they deducted for ADSL and landline services and they should revise the current invoice as well. If they are not willing to do so I want to cancel my connection and take this complaint legally.
