10 mbps Uncapped ADSL not working properly

I know I am probably wasting my time here but here goes.<br> <br> I have been having endless issues with my adsl since Dec last year. I am on an uncapped 10mbps line. My modem used to sync with the exchange at 10mbps. When I started having issues I noticed it dropped to 8mbps and then 6 mbps. The technician confirmed that I live 2km away from the exchange and should be synching at 10mbps.<br> <br> The issue i have is that when i do a speedtest the results are Ping: 2000ms, download: 0.5mbps, upload 0.33mbps. When I first upgraded to 10mbps if I did a speed test the results were ping: 18ms download: 8.5mbps and upload: 1mbps<br> <br> The technicians work on it, say it is fixed and close the call. Because it is not fixed I have to log another call and go to back of the queue again. I am now on my third call for the same and getting nowhere. I have been patient and wanted to give Telkom the opportunity to sort out the issue before drastic action like cancelling my line. current ref number 786crk120216.<br> <br> last opportunity to fix my problem!
