Telkom account cancellation

Hoorible service, I moved and they did not support adsl at new premises, which I understand. I then phoned to cancel my account. The cancellation date with notice was 09/09/2018, yet they billed me for the entire month of september, when I phoned they said that I will receive a credit on my next account. When I received my next bill, they charged me for another month on top of that, another phone call, they stated that my account has not been cancelled, yet I received a confirmation email stating that it was cancelled. They said that the account will be rectified and they will phone me back with the result, more that two weeks now and still no answer to resolve this! There are many new internet providers, I would advise to rather consider them.
