TELKOM IS THE WORST EVER!!!

I have been battling since January 2020 to cancell my Telkom account, my line was suspended December 2019 and have not used it since, i called telkom to cancell my account and told the lady i will pay it up as i know i owe them for the months of Nov and Dec 2019, but nothing happened. Yet i am receiving a bill every month for something i am not using. Email after email and call after call nothing gets resolved. During the month of May i got an email (finally) saying i should forward my details aswell as an id copy to cancell it,which i have done,but still i am being billed. How can i be billed for a service i am not using or benifitting from? I was told that is just how Telkom works,i then requested a copy of my paper work where i signed and agreed to this as i was told it was stated in the paperwork,but not even that was sent to me. I feel it is very unfair that Telkom overcharges people abd gets away with it!!! All i want to do is pay Telkom for the months of November and December 2019 that i owe them and cancell my line with them!!! IS THAT TO MUCH TO ASK??? I have all my emails printed etc showing how i have been trying to resolve this! PLEASE DO NOT USE TELKOM AS YOUR SERVICE PROVIDER!!!
