Why so many “intermittent service interruptions” !!!

I work from home and have been with cox almost 5 yrs now. In the last 2 yrs, both summers (during our busiest times) I have experienced NUMEROUS “intermittent service interruption” issues as well as “maintenance” issues causing my internet to go down and not be accessible. These “issues” are everyday and can last almost a month! 

The type of work I do does not allow me to just sit idle, while cox figures out their issues while I’m paying almost $200 for mediocre, subpar internet! 
And you can never get a clear answer out of anyone because you can never get to a person high enough in the food chain that actually knows what’s going on. 

This is insane and unacceptable… highly considering switching at this point. I’ll pay the almost $200, if the internet ACTUALLY WORKS.
