2 weeks later and line is still a problem

Have been logging calls since 2nd December 2015 with problems on the line. I have a 4mb adsl line. The line syncs fine at 4mb but when I do a speed test I get a line that is less than 1mb. Cannot view an online content due to slow line. Technicians come out to fix and close the call. I have to open a new call everytime as I cannot wait for somebody at 10210 to answer and reopen the old call. Finally a technician came out on Monday ****h Jan 2016) and tested the line with Telkom's Dlink router using the telkom guest account. Once again line sync speed is ok, but cannot get to 1mb when doing a speed test. He was going to chat to somebody else to help on TUesday. Just called the technician and he said he is not working on the call as he has been transferred to a new dept. What I am to do now wait another 2 weeks with no line ?
