Service Outage while working from home

I am literally working and the internet service goes out. This is such a major inconvenience. It says won't be finished until 4:39, I'm off at 5. Xfinity wifi is not secure enough for me to use on my work laptop. No warning was given. Highly considering switching to another ISP, this is ridiculous and you can't even speak to someone. What do I tell my job, Xfinity is down for 5 hours????
