Terrible Cancellation Support from Telkom

Phoned Telkom customer call center for cancellation of two mobile numbers that I received with an ADSL Line. The mobile numbers were never used and no longer on contract. Initially I cancelled all my Telkom services in April 2018. For some reason two mobile numbers were not cancelled as requested. I continued to pay R100 a month for these numbers. I phoned the call center on 23/10/2018 for cancellation and was helped by Cindy Candice Goliath who informed me I have to fill in a cancellation form and mail to ***, this was filled in and sent on 23/10/2018. In January 2019 I received a bill yet again for the mobile numbers. I sent the cancellation forms again this time to *** which is shown on the cancellation forms. Up until this date no reply has been received from Telkom. I continued receiving bill notifications and sent the cancellation forms again on 18 Dec 2019. I then received another notification from Fathima James regarding outstanding fees on 15 January 2020. I was informed by Fathima that a dispute will be logged for the charges. Telkom continues charging me for service that has not been used since April 2018. Why should I pay for a service that was cancelled in 2018 but I am still being charged still in 2020. I received a new notification on 11 Apr 2020 after I informed Fathima again on 17 Mar 2020 that I was still being charged. This is ridiculous and the cancellation process unnecessarily made difficult by Telkom. I will not be making use of any Telkom services ever again.
