Billing & Subscriptions

It's been more than a year trying to cancel Directory Services Charges of R110.58 on my account, no one but no one can assist, it does not reflect on the contract at the call centre. How is that possible?? I've also subscribed to the unlimitedhome 4mbps - R599pmx24, and still nothing. Cancellation letter for a line has also been sent and still no cancellation but I have to pay otherwise they cut all the line and internet. My account is still the same and the new services has not been updated. No office to visit, how convenient for client service providers, this is unacceptable as we pay for the services, but there is no service. Seriously need someone to assist in this matter.
