ADSL Line Up and Down for months

I have been struggling with my ADSL line for the last 3 months. I am paying for a 10Mbps package which can hardly run at 8Mbps due to the bad telkom network infrastructure. My latest fault 664CTK190315, the 6th one reported from January was attended to on Sunday. the technician told me that the problem was somewhere else. he left and never came back and my line has been completely disconnected since then. I am unable to reach your call center or use the online chat service, no one ever responds. Please can this be attended to and why does telkom not over a 2Mpbs/6Mbps and 8Mbps connection option seeing that they cannot provide the service that they advertise to all of there customers. This is the last straw if this is not resolved asap I will have to find an alternative. Paying more for decent service is a better option than no service.
