MWEB lights are on but no one's home.

We have had our fibre internet connection with Mweb with absolutely no issues at all until this week. I teach from home so I value my internet connection like gold because it is my bread and butter. On Monday morning out of the blue just before I was about to start work the internet went off. Everything working fine and no internet connection. We then logged a call and managed to get things sorted but had missed 2 of my classes. Then yesterday afternoon at 13:00 the exact same thing happend and now we have been off for 17 hours with absolutely no internet connection. And the call centre in this situation has been very unhelpful and we still waiting for a call back. I am so very dissapointed in Mweb, I expected better. Shame on u
