POOR SERVICE AND NO FEEDBACK

I am experiencing poor speeds on my ADSL connection. Not even half the connection speed that i am paying for. I was phoned by mweb about a year ago and told that i could get better service if they managed my telkom line. With that being said, i now open a new call, since they get closed without any feedback, every two weeks to try and have the problem resolved. I get the same response every time \that it is a problem on the telkom side
