Cannot work from home, Xfinity Broadband unreliable [Please view description as there is a lot of information]

I do IT for a living and require my services to constantly be active, for the past month Xfinity has been absolute garbage. If you guys did not gridlock everything in the tristate area I would probably get fiber and drop this mess. On to the issue though, when using the xfinity network, I have attempted to ping Google's DNS [8.8.8.8] with a "request timed out" over and over:

C:\Users\godli>ping -n 10 8.8.8.8

Pinging 8.8.8.8 with 32 bytes of data:
Request timed out.

Ping statistics for 8.8.8.8:
    Packets: Sent = 10, Received = 0, Lost = 10 (100% loss)

I have even turned off all of my antivirus, turned off all firewalls and attempted to ping also with no success, I just swapped out the modem as recommended by Xfinity [which I already knew was NOT the issue but for some reason support makes you jump through hoops and waste unnecessary time to get to the actual issue]. I had a tech come to my house on 7/24/2024, did an amazing job switching out the coaxial that runs from the modem to the outside box on the side of my house, removed all splitters from previous setups [I do not have cable]. He noticed that the person that lives above me had water in their line to the box outside. I tried to speak with support letting them know the process of elimination would be the best thing here [I am able to connect to the modem all the way in the basement but cannot connect to my own network/modem 5 feet from me and hardwired????] I can connect to websites and everything works just fine, only when taking calls or doing something that requires a constant flow of packets is when my network is shot. My kid gaming? FORGET ABOUT IT, SHOT!

I'm stuck attempting to use a VPN because somewhere in Comcast's [Edited: Language] network [gotta be the tap or the node] everything drops for some reason. I am able to ping connecting a server in New York with 15-25 ms latency w/vpn it makes absolutely no sense.

This has literally almost cost me my job and If I lose my job because I pay a bill every month and I'm not getting the services provided, I have no problem holding Comcast accountable, I have nothing but time on my hands at this point.
