Telkom ADSL Cancellation

I upgraded to a fibre line early in 2017 and tried cancelling my Telkom ADSL account by emailing a cancellation form to Telkom, which was the required method back then. I never heard back from them. When I tried again I was told the process could only be done online but was not working at that time. When I tried again a few weeks later my services were suspended (I reversed the debit order since I wasn't prepared to pay for a service I no longer used and couldn't cancel) so I got in touch with a telkom representative and was told to forward my email cancellation to him which I did but he also never go back to me.

I have tried multiple times to get in touch with Telkom and they always tell me some one will be in touch but i never hear back from them.

Now i have NuDebt phoning me everyday.

Please can someone from telkom resolve this issue?

Thanks.
