Did I make a serious mistake switching to RSAWEB?

I heard that the RSAWEB service is good and I decided to switch to this fibre internet service provider. My experience is however different so far. I first received an email to say my service is now live, even before I received the hardware. I received a call to ask if RSAWEB can courier the router or should visit the premises. I asked them to visit and assist with the installation. Then a router was delivered by courier, without another word. I did the installation as instructed, however, there is no internet. I tried to call for assistance, without success. I then sent an email to the email address provided. Absolute no response. I am starting to seriously question if I made the right decision to switch to RSAWEB.
