Telkom Internet the pits

We moved to our home in Radiokop on the 20th Feb. because there were no lines we luckily took over the current adsl line. Well it hasn't worked since day one. Doing a speedtest we lucky to get 0.12 upload speeds. Try watch a video it said sorry signal to weak. Telkom blames Mweb and visa versa. Now the Internet has been cut completely. Do they know the cost for 3G data ?????? I work from home so my work is seriously affected. I got a call today to say they cut the line because they switching over to a new exchange which can take 3 weeks minimum ??? Seriously how am I going to do anything. Maybe time to switch over to another supplier. Oh and I pay every month for nothing
