ADSL LINE TERRIBLE

I do some work from home and reported the ADSL line fault on December 11th 2017 (fault reference no: 1947CRK111217) and have had no feedback and have to suffer a line that is supposed to be a 10 - 12Mb line and is most of the time dropping and if it connects the fastest speed is like 3Mb if we are lucky. Called the Telkom help desk / Fault reporting a couple of days ago after many attempts it was finally answered. The Lady I spoke to said that a technician was not even assigned to look at my fault yet. I understand that it was over the Festive season but enough is enough and I am not happy that nothing has been done in over a month. I had a very stable line with Telkom, up until they upgraded the area now it just adjusts the speed according to the attenuation on the line, which has progressively gotten worse over time. I have been in Telecommunications for Almost 30 years now and cannot accept this bad service and absolute disregard for a customer. If there was an alternative I would change in the blink of an eye. But we are left with no alternative but to beg for a better service. Please can somebody attend to my complaint with some sort of Urgency and provide me with the service I am paying for which is fastest ADSL not slowest ADSL! Have now logged about 6 times the fault latest *** and no joy!!! Line is desynching and has like 1000+ ping! Come on guys please this is ridiculous!!! Best Regards, Jason
