Frustrating Trudon and Telkom

I have been dealing with a lady called Harriet Mdluli from Trudon. A week ago (4 February 2021) she said my matter has been sent to the cancellation department. That was the last time I heard from her. I still have not received any correspondence from the cancellation department nor any feedback from her. So at this point, I am even sure that Trudon's cancellation department has even received my request.

I have also sent an email to Telkom to *** on 29 January 2021 but have never even received feedback from Telkom not even an automated response to acknowledge that they have received my e-mail.

As far as I am concerned this matter should have long been resolved. I don't know why this has taken such a simple matter this long to be resolved. All I need is for Trudon to confirm my cancellation so that I can inform Telkom to stop billing me going forward.
