Telkom ignores request to cancel and keeps *****ing from my account.

I emigrated to New Zealand at the end of January and requested that Telkom Cancel my account. They told me there would be an R1908 cancellation fee and suggested I reduce my account from R759 a month to R60 a month for the remainder of the contract, which was until April 2020. I agreed to this and was told that it would be done.

Instead, I have continued to be charged R759 every month and have just received another bill at the end of May for R705!

As I am not in South Africa I can't simply phone and in any case, the call centres are closed and my emails go unanswered. They are now *****ing from my account with no way for me to stop it
