Latency in Boksburg

Since the 19th I've seen high latency on my line (ping running between 150ms to up to 500ms). I've reported this and have had to explain to 3 different people from Telkom WHAT latency is and then hearing that a technician will be send out within 24 hours. Well that never happened (big surprise and yet again a day wasted waiting for Telkom to arrive). <br> <br> So I phoned Telkom late yesterday afternoon and was advised that the technician is working on it at the exchange and will phone me to advise to test my line. This ALSO never happened and last night I sill experienced 150ms+ latency. I mainly use this for online gaming, but this high ping makes it useless to play. I can only imagine how the people must feel who do online trading from their home ... Yes .. the stock market prices changes within 500ms and what you buy for and finally get could be a huge difference.<br> <br> Please can you advise when this will be sorted & not make promises you cannot keep (i.e appointments and return calls). We are paying for a service that you are not delivering.
