Ongoing ADSL fault not being resolved

I have had a fault on my ADSL line since 18/12/2017 and have followed the correct process and logged a call to have Telkom fix my fault. I have logged a call four times and each time, the fault is closed without fixing the problem. Each time I have followed the correct process but the technicians keep closing the fault. Below are the fault references for the faults I have logged: -

18/12/2017 – 652CRK181217 19/12/2017 – 429CRK191217 20/01/2018 – 206CRK200118 28/02/2018 – 458CRK280218

I will try Telkom again today but don't see the point because the technicians will continue to keep closing my fault without resolving the issue. Usually, when I have a fault, a technician comes out to my house to resolve the issue. Since 18/12/2017, I have not had a technician come out to check my fault. Is there any other way I can log a fault where someone will actually look into my issue and resolve it once and for all? I am going into my third month of not having ADSL.
