Continued charges 6 months after cancellation

I cancelled my account with Telkom 6 months ago, and have been getting billed ever since (including being handed over) despite 7 attempts to escalate the matter. My last attempt to open an account dispute resulted in further charges, including, unbelievably - a reconnection fee and unrelated charges I know nothing about.<br> <br> Please, I beg you - I have long since settled my due payments - remove my accounts from the system and stop harassing me about a service I no longer have or care about.
