Unable to cancel ADSL or get feedback regarding it

I have been struggling since March 2018 to get my ADSL cancelled, but with no success up to date. I also receive a billing for it every month and I it is not even in use currently. I also want to cancel my land line now.

Since March 2018 I have sent numerous emails to cancel my ADSL service. I have completed the form and sent it to the requested email as instructed to. I only receive an automated response. I have not had any official feedback on my request. I have resent the mail numerous times with no result. I have tried the chat facility on the website and the operators on there tell me they can't assist me, only somebody from the cancellations department can, but there is no way for me to contact anybody in this department. Numerous phone calls have also been placed and the operator on the phone is also unable to assist. I have even been to a store where I was told that they can't help me there either.

It is absolutely ridiculous! Nobody in the company is able to assist! Do they even know what they are doing?

I refuse to pay any further bills I receive as I have done my part, but Telkom however has not!
