Poor service

on 10/08/2018 I informed Telkom about a DA Capped line that they are charging me for. I do not use a DSL line as I have been used MWEB for years now. The immediately send me a form to complete and we did as well as send it back immediately. I have been followed it up with them and yesterday I received me Telkom account and yet I am still billing for the lines, this is more than R500 per month and this is going on for months now. I want you to see what you can do as no one is coming back to me and this account need to be paid
