I think that's balanced out by the person who literally speed-read a canned script at me and then immediately hung up.

Yikes! That person had clearly used up their level of Care™ for the day.

Internet service in America is terrible, I have to agree. And even when you have a plethora of providers, the practice of merger/acquisition is guaranteed to reduce choice to only one or two (as has happened in my area--I was with Verizon until Verizon was bought out in the area by Frontier, and I've been with Frontier ever since. Frontier sucks, but not as badly as Spectrum). I hope you get your service back soon, but I'm glad you have a backup via tethering!
