If that's true, then at this point I would personally paste (ie, I suggest pasting) daily traceroutes/speedtests comparing VOX with another ISP (such as Telkom's guest account, if you don't want to pay for another one). That way you can prove that it is a VOX issue. But to just quote "Telkom have confirmed" only to hear VOX retort with "It's a Telkom problem" in ping-pong fashion, will get you nowhere pretty fast. Quote some comparative traceroutes on the thread, conducted between different ISP's at the same time of the day. This can help others out too who may suspect that VOX is to blame, and should persuade any VOX techies browsing this forum that there is a problem on their network, assuming this is the conclusion that the traceroutes point to
