ACCOUNT CANCELLATION

I have numerous times tried to cancel my account after Telkom suggested this. I have done a HelloPeter and someone called me from Telkom to resolve the matter, however it has still not been resolved. I have been threatened that Telkom will blacklist me if no payment is made to them. I placed a stop debit on my account due to this being Telkoms fault, and this month Telkom has changed the amount and once again debited my account. I am fed up and this matter needs to be resolved immediately. This is disgusting and Telkom offers absolutely NO customer satisfaction nor any form of service.
