Poor connections

My Fibre internet has more downtime than any thing else. I rely on internet connection to work from home but nearly everyday is a challenge with connection. I'm paying to get 40MB/s but I get 0. Everytime I contact my ISP I'm told the issue is with VUMA Reach. This is not fair I'm a paying client. Surely I need to receive the service for such. I have uninterrupted payments I expect uninterrupted internet.
