Short answer to "what do I do? "

Most of these, outside of power-cycling the home router (I presume you are talking home service. I use spectrum but only for the phone's cell service) are kind of techie, so

A. Try to get spectrum to replace the router/modem, since you are probably renting it. Say it's broken so that lazy techies can't give you the run-around.

B. Call the authorities. I once called the local FBI office when there was an office hack where I worked. They may be working on an organized attack, trying to find out who done it. Especially if it's Russian. DOJ/FBI are eager to bust Russian and Chinese organized attacks.

C. Geek Squad might balk, but try to get your money's worth. They may know how to diagnose and restore a hacked home router.

Geek Squad can probably give you a cheat sheet on what to do after a hack. Articles on the internet vary widely.
