Horrible Service, and poor customer service, Xfinity? Silent and provides ZERO resolution

OK - here it is - all of it. 

Internet was perfectly fine until 4-5 months ago. 
I have a home-business (WFH in Tech, My own Company) - I have the highest plan $120 dollars/month. 
I live in Sunnyvale, CA. 

My downloads go from 1200 mbps/45 Upload --- to 200 mbs and ZERO (yes zero) from 6 PM to 2 PM - on most days without fail, which has been happening consistently for over 3 months. 

I've called Customer Service countless of times (take a wild guess what they do and say): 

 - Reset Modem, yada yada - like the internet isnt a crucial part of modern society and somehow we're all seniors (Im 42)

They have sent TWO techs to my home: 

- First Tech: Super friendly and nice, did everything he could, however, the internet promptly went to [Edited: "Language"] -- he did tell me there's "Noise" in the line, and there should be escalated. 

- Second Tech: HORRIBLE, cussed at me, was annoyed at his work/comcast/Xfinity - didn't even want to enter the home, to check for issues, told me to just "Credit" the account and keep doing that until they get a "resolution" - fought with me and was incredibly unprofessional I had to record the whole interaction (and I have it on video - including his license plate) 


Then was referred to a man named "Too" - which gave me his phone number, told me they were "Re-wiring" my "Whole area" - and that it would take two days. 

Its been 3 and a half weeks. 

I cannot submit my work at night, download my software builds, work in general specially since software is constantly pinging the cloud to see if its "legal" these days, so I keep getting disconnected and since I have no internet, my software keeps saying to "SAVE" because the service keeps dropping out. 

I want to be ABSOLUTELY CLEAR HERE --- I cannot Work, at all. 

I've mentioned this to Xfinity a million times, this is why I have the higher package, and this is why I pay $120 dollars every month (and going up more every year - $15 this year more) 
I drop video-calls all the time, I'm starting to worry about my own Job security - thanks to the poor and declining service I get - and yet, I get no refund, and I get no resolution to my issue. 

So change right?

Unfortunately, NO ONE has internet in my area, and Comcast/Xfinity has overbid all providers - so I am stuck

Lastly, as I mentioned - I am a working professional, I am NOT complaining about HD Youtube not loading, or Netflix HD not being "Crisp" or even IG not "loading fast" like 99,99% of all calls. 

I cannot work, I have called several times, and Comcast seems to NEVER help me, and whats worse? I cannot even switch providers.

Truly like in the Tags down there - #horrible #customerservice - and whats worse as well? 
Somehow everyone that calls them? gets treated like a baby who doesnt understand the "complexities" of internet signal - in the San Francisco Bay area. 

in 2024.
