Can't Manage Account

I am trying to start an internet plan for a new apartment. I got no information given to me about the installation or the plan at all. I am not even sure if it went through, however, I can't check if it did on the website because none of it works. The account page fails to load every single time. The manage plan page constantly reloads and never shows anything. Even the pay bill page doesn't work. I tried clearing cache already. I tried to use the app but it says I need to have xfinity to use it. I have seen many other people complain about this same issue. It is completely unprofessional to have a website that never works as an internet company. Not even the AI embedded into the website knows how to do anything or even works half the time. Fix your website.
