Telkom Adsl and Landline

Ive been with Telkom for about 3years now...so i decided in august to change my service provider to Afrihost due to the good support they offer and a feedback from people in my area.So i called up telkom asked them to cancel the home basic adsl that i have and they said no problem,but they went and canceled my whole package adsl and landline.Then in october they corrected it only for the last few days of the month and cut everything off again in the first week of november and have been paying since august for internet and a landline that i havent been able to use...according to telkom my line is canceled and active at the same time so its off but i must pay for it..then after speaking to billing they said i dont have to pay because i was to be credited for a payment or two i get reported by telkom to the credit burrow for not paying....So this has been a huge hasle and no one seems to be able to resolve this for me its costing me money and i cant use it and my name is getting slandered because Telkom has no idea whats going on....
