Telkom the worst customer care

They not even worth a star, bad communication. I cancelled our contract in November 2023, received a reference number but still they try to put a debit order through. Numerous times I had to reverse the debit order and no emails not phone calls are helpful with this issue. I only get reference numbers but no action, I were even handed over and still the dispute is going on. It seems to me this problem is a general problem customers struggle with. Telkom really need to start listing to the "so called" recorded phone calls and emails.
