Is there just one person in Telkom?

Is there just one person in Telkom that actually knoes how their systems work, are able to diagnose a fault and then knows how to remedy the fault? Every single Telkom employee and/or technician I have had the misfortune to have contact with seems to know less than the previous one but that does not stop them from given my a b/s diagnosis of my 'fault' yet not one of them have been able to fix it. For the past six months this has been an ongoing saga with the last two months being plain sailing untli the technicians, on a lovely Sunday morning three weeks ago, decided to replace a cable nearby. Since then I have been unable to use the internet other than at a slow crawl with my ping hovering between 800 and 1200 ms. I want you to please contact me and put me out of my misery by just cancelling this service. I really have never come across such ineptitude. The most recent ref no is 78LTK121115
