Faulty exchange - no help

For the past THREE months I've had numerous speed and especially latency problems in the Cape Town CBD area on . After running several ping tests and trace-routes which displayed the same issue (namely that there's a high likelihood that there's a faulty board in the dslam. <br> <br> Telkom support didn't know what I was talking about after the first phonecall and decided to just reset ports which didn't help matters. Two phonecalls later I got to speak to someone that understood the difference between latency and speed (compliments to Mokhotla you need more people like him). <br> <br> After matters escalated to technical team things went nowhere and only got a ticket informing me that ticket has been resolved (It has not been!).
