Unresolved WiFi connection problems

I have been having issues with my WiFi connection for almost three months now. On the 19th of February I logged a fault report after I had called Telkom the previous week to advise of the issue and they tried to fix it remotely and it didn’t resolve the issue. I have been called about 4x times now by their technicians trying to resolve the issue remotely and the issue is still persistent. I was then advised a technician will be sent through to my home to sort out the connection problem and till today I am still waiting for a technician to show up. In the meantime I am making full payment for a service I am not receiving. They seem to be dragging their feet when it comes to sorting out the issue.
