Telkom not assisting to Sort out Billing Account

I app**** for an ADSL package in January this year, accidentally I app**** for a complete ADSL package instead of just the Fixed Line service. I immediately called Telkom and asked that this package be cancelled as I would only like to apply for the Fixed Line.

Telkom informed me that the package has been cancelled. 6 Months later I am still being billed for the full package. I have called and online chat previously to cancel the package, which I am each time assured has been done. I am still being billed.. Each.. Month... I pay each month just enough to reduce my Credit Limit up to a point where I can use internet. I have not used even 1 MB of the package I am being billed for. I've logged a Dispute to get Credit on the outstanding amount and only apply for the Fixed Line. Nothing is happening, no one called me or sent me anything. USELESS SERVICE!!

I am so frustrated, no one can help me. If anyone reading this needs internet, do anything you possibly can to AVOID Telkom.
