Supersonic fiber

I have received a very poor service from supersonic fibre Starting From The Call Centre to their technician that came to do an installation of the fibre router in my home. firstly I gave access to their technician who was at the gate to install new router for fibre access, I gave them access into my property ,The technician didn't give me a call to ask where do I want the router installed. realising that I was not receiving any call from the technician, I called my helper to ask if the technician is still around ,so that I can tell where I want the router to be , She told me he was already gone, I called The Call Centre immediately to assist me to tell the gentleman that came to do the installation that he had installed the router where it won't be useful to me since I wanted it where there is server Im my attept to get her from the call center they dropped my calls several times, some of them they would say to me just hold or let me Investigate hold on,they will never get back to you ,instead they will mute my call for over 20min,and this happened multiple times.My fiber was installed last week Thursday, so you can imagine how frustrating it is to have that you cannot use maximally yet you will be paying for it fully.

This is a cry of a man that need help from those in charge because I have done everything possible to communicate to them without any attempt to assist me. I want router to be taken out from where the technician has put it to the server where I want it because where the router is it is useless to me I'm not in a position to use it maximally
