ISP Data Center proxy ip address issues

I have discovered that Xfinity uses data centers in certain cities and routes residential users internet data through these centers which generate proxy IP addresses. I am an avid sports fan and use sports apps on my smart TV to watch my out of area teams. I have run into an issue with the IP address assigned to my home network. Xfinity has assigned my home network an IP address that, using geolocation, locates me over 200 miles from my actual home address. all of my sports apps have begun blacking me out of games that are in the Location of the IP address not my actual address. I have contacted Xfinity 5 times and been told the issue is being fixed without anything ever being done to fix this and give me an IP address that matches my geolocation.

I am at my wits end and my next move is to end my relationship with Xfinity and find a new ISP.
