Bad service on a new application at Telkom

I filled in an application for fibre wifi, in a house where it is already installed. he previous owners left all the hardware here, in perfect working order but just deactivated their account. I received a call telling me the technician would be here the following day so I sat at home waiting. When noone came I called into the telkom store in Ballito Junction.They informed me that the technician had been and there was no response. He had also called an old number of mine that he found on an old application, not on y new application. Now I cannot get anyone to come and install for me, I get paid by the hour and I a losing days of income, not just hours. Noone at Ballito Junction store can tell me when the technician will be here, they just say there is no technician in the area and so I sit, having cancelled my previous wifi in anticipation , but now it looks like I won't even have it by Christmas when I would like to be able to make zoom calls etc.. to family but I need my wifi. All the hardware is here, I just need someone to come and switch me on but noone at Telkom seems to care!!!How do I find someone to actually give a damn and come and connect for me????
