Service and billing nightmare!

My ADSL service that i had from February till now was off for 4 month out of the 8 because of a technical fault. I also have a cellphone connected to the land line for which i was given the wrong contract! In trying to rectify the problems over the last 8 months my land line and with it the cellphone has now been disconnected for the third time. So that would amount to R1200. I pay almost double for a contract i didn't sign for and the staff at Telkom direct at lakeside mall in benoni where i bought the contract are very unhelpful! Calling 10210 is also useless because not much happens from from their side either. Can someone please call me to sort out my many problems? A telkom agent called me on Friday 13 November to confirm my land line cancellation. When i explained my problems, he said his supervisor would call me back on Monday. As always no reply! What now Telkom? I will not pay disconnection charge while waiting for you to sort out your problems!
