Telkom is useless

I relocated my adsl line over a month ago. When I relocated I was only getting a download speed of 1mb when I am paying for a 4mb line. I have logged 10 faults because Telkom just keeps closing them and saying they are resolved when absolutely nothing has changed. Thy have sent 2 different technicians to my house to see if the problem is there but is not they know the problem is the cable going back to the exchange but they refuse to fix it. Another technician came today and I don’t know what he did but now my download speed is 0.02 mb so I have absolutely no internet. They keep saying to me that they are evaluating the issue but NoTHING gets done. If only I had another option because it is the line going back to the exchange that is faulty so doesn’t matter if I changed service providers. Telkom get your act together and sort out my internet tonight!!!!!!! I’m tired of chasing after you can someone stand up and take some responsibility and fix the line. Telkom belongs in a backend 3rd world country that’s how they do business they have no place in SA because they have no standards. I need this fixed immediately or I might as well cancel my contract. Telkom has also made me pay full price for 4mb line while I only have a 1mb line for the past month. And if I don’t pay then I get phone calls saying they are going to cut my line. So I must keep paying 4mb line price in order to get my 1mb line which is now 0.02mb in order to have some sort of connection. This is my last option I have no where else to go to geet this resolved.
