Pathetic Service - Cancellation of DSL

This is a complaint with regards to the service I am getting from Telkom. On the 6th of October 2020, I cancelled my Business Elite DSL package and sent an email to the *** address, because there is no way, I can access the online Portal to do the cancellation. The email was sent, and I received an email in return to say that Telkom has received the cancellation. In November, I receive the bill and pay it, because of the months notice. December I receive the bill again, and the charge has not been taken off the account. I phone Telkom and the cancellation has not been attended to. I speak to Thumakaneni on the 24th of November 2020 and send her the cancellation email '***', and pay the account, because my Internet and Telkom line is joined to the same number. To make double sure that the cancellation has been attended to, I again contact Telkom and speak to a lady and she tells me to resend the email to '***' and I also send it to '***'. They advise that they have sent an email together with the cancellation email to the cancellations department and assure me that the matter will now be resolved. I now receive the January statement and AGAIN the charge has not been credited to my account. I speak to Nosipiwo as at today's date and she eventually provides me with a reference number. The problem is this, if I only pay the account less the DSL charge(s), they will suspend my line. No one can provide me with a contact number or email for a manager. WHAT MIRACLE NEEDS TO BE PERFORMED TO HAVE THIS MATTER RESOLVED!!!!! Someone from Telkom please messenger me the information for someone I can contact that is higher than the complaint or escalation department staff. This is now beyond ridiculous!
