Unbelievably Slow Website

I dread anytime I have an issue with Xfinity billing and have to actually use the site, it is unbelievably slow. You're the most expensive ISP in my area, with the worst customer service, and the slowest website I believe is possible. My natural gas website is exponentially faster than yours, my CITY'S website is exponentially faster than yours. Having to order things from ULINE is exponentially faster than your website. I don't know if it's an accident and a result of true incompetence on the Comcast side, or if it's meant to be a South Park style punishment for having Comcast, but it is truly wild. 

I just want to pay my bill, I guess I'll try again tomorrow.
