Telkom are inadequate!!!

Upgraded my 2meg line to a 4 meg 6 months ago. Many speed tests done and only getting 1.9 till this day. I have logged many technical logs and spoken to so many different people (Trained Parrots) even had a technician visit my premises who confirmed the faulty line but could not rectify. I requested to hold monthly payment back or even pay for the service I was receiving (2megs) and credit the difference Told to speak to accounts who would help but had my line suspended until account (2months) payment was settled which by the way has been. Now Ive been holding on for cancellation for over 40 minutes on the phone. Absolutely terrible service paying for a service that is falsely advertised and with all the trained people in the company still no one is willing to give of their best to meet a PAYING CUSTOMERS NUMEROUS REQUESTS to sort out a service that they have promised to deliver. Telkom \Deal with one of our many hundred telephone parrots who we have trained to pass the buck and brush you off"Absolutely useless!!!!!! Absolutely unhappy!!!!!"""
