Telkom continues to let customers down

I cancelled my account four months ago because I moved house and since then Telkom has still been charging me for an account which I no longer have access to. When I try to follow up on it I get no response for them but they've been happy to continue debiting my bank account. They are an embarrassment to the very idea of service delivery as they seem to have no concept of what this entails. I'm very sorry to have signed up with them in the first place.
