I really feel for you. After Comcast, we moved to an area that only had Windstream, which is a whole other circle of hell. Now we have Starlink! It's amazing! 🙌📡
Here's a valuable tip someone shared with me. Do a search for whoever oversees your public utilities in your state, probably something like "Public Utilities Commission of *insert state*". They should have a complaint form. Fill it out with all of the facts of your service problems with Spectrum- wait times on hold, wait times for service calls, how often your service goes down, etc. No emotion, just facts.
Getting one of these complaints is a big deal to these corporations. I did this on my state's website for Windstream, and twelve hours later I got a call from a Windstream executive. She had a tech out later that day and the problem was finally resolved (at least until about 10 months later). She also gave me her number to call first if I had any issues. No other major problems after this. Your mileage may vary, but I hope this helps.
Once Starlink was available in our area, we couldn't cut Windstream fast enough. 😂
Anyway, good luck with your internet issues. And let's hope Royal gets their act together soon!
