Wow the hostility. Relax.... Realistically what answer did you want? There is zero trace routes to help any way no speedtests no investigation or anything from your side and even if the Rep was still on the forum what would be the difference compared to 10210?
Post a trace route to see where the latency is happing. If it's happening on the 2nd/3rd hop the it's likely IPC capacity related which is it very likely is. Just like other ISP's Telkom need to apply/buy more IPC capacity from Openserve and wait for Openserve to install that capacity. Just because Openserve and Telkom is the same company they have to follow the rules as silly as it sounds but that is just how it is.
So from your side test with another adsl account and see how it performs on the line. If it's fine then you know Telkom ISP and then it's basically just a waiting game and it's a pity that
@ranger left Telkom because he could have actually looked into it for you and reported back.
