Telkom improper billing and poor customer service

Improper billing for optic fibre line for 2 years by telkom has been a thorn in my flesh. This is in spite of several.complaints via telkom customer call centre and Twitter service, all of which became fruitless. Each month of my statements has been charged an additional.amount of R503 which they say is for the third party yet the contract I took was on.special i.e., the fibre line was free. Instead.of paying R1079 as was advertised..telkom.billed me monthly payment of R1700 and sometimes.even more than such amount. Last year between June and September they promised to address this matter after I insisted that I want to talk to the costerm manager. However..after few months.the same problem.continued and now they said the mistake was made by the sales personnel who was filling the contract. WhenI go to the telkom outlet at the Bayside.Mall in Cape Town, they re unable to help.me as they say they re.not involved in.billing matters. It is so disturbing as this is the place when I took.this contract. Right telkom owes me.money because I was forced to settle the account to avoid disruption.of this service and being blacklisted for not honoring the payment.

I dont know how this matter be resolved as the bill is still accumulating. I have cancelled the contract. But they re not closing it..the telkom.is unduly billing me.monthly which further affect my credit status as I cannot pay for service that I dont use.
