Terrible Service

I logged a technical fault with Telkom 2017/10/17 stating that the Network is very slow and that I am not experiencing the full potential of the 4mb line. The consultant at the time explained and confirmed that I was supposed to be getting download speeds of 3.5mb and 4mb and upload speeds of 450kb to 700kb per second and upon trouble shooting and testing the router with them, we confirmed that we not getting those speeds. The fault (102CRK171017) was logged and I was advised that a technician will be sent out to assess and possibly resolve the situation. To this day, a technician never showed up. Another fault was logged (156CRK130218) was logged and the same process followed. When contacting them again 2018/02/22, 23, 24 & 25, they advised me that a technician was at my place and that they contacted me 2018/02/19, to which i advised them that no one was here nor did anyone contact me. They proceeded to make notes on their system and advised that the technician will be informed and that I will receive the required assistance. I called again today 2018/03/02 to advise them that I am experiencing yet another issue with my router in that it now doesn't connect at all and explained that the DSL is flashing. I also receive a error message on the router interface stating that the router is not syncing. They advised that they can only escalate the matter and have a technician sent out. I am now frustrated at the level of service received from Telkom as well as their lack of communication between departments/ colleagues as each person I speak to provides a different story. I don't even have this line for a year yet and this is the service I have received. Also note that this is no cheap line as I pay over R600 for a contract that supposed to be R599 fixed per month as per Telkom
