Pathetic service

I have cancelled my Telkom account two months ago as we have relocated. Telkom still continues to bill me. I have been given two reference numbers over the past two months Reference No. ***A Yet I am still being billed for a service that I am not using. This is nonsense and demonstrates the incompetence of the people we are dealing with. Can someone get back to me ASAP, via email as I no longer have a South African number.
