The worst internet service

This is absolutely the worst internet service I have ever had and I have had a few different providers in the past. My internet goes out several every single day and we have to restart our router 2-3 times EACH time it goes out just to get it working again. We’ve had people come out before telling us there’s nothing wrong, they’ve fixed it. But it’s not fixed. This is absolutely ridiculous. I do a lot of work from home so this makes everything extremely difficult.
