POOR SERVICE

I app**** for Fibre in my home, the technicians came and installed it on Saturday 06/05/2023 and I received delivery of my router on Monday 08/05/2023 when I am trying to connect - I am unable to connect, it's giving me ''connected without internet'' - so I've logged a case with the contact center (case number ***1) and it has been 4 days and I don't have access to my internet. Please assist.
