I have spent hours stuck in Xfinity ID Login Loop

I'm trying to set up internet service at my new home. I've had an account with Xfinity for many years but haven't used them for over two years. I got a plan set up and all my billing info in. Then I clicked order and it just sent me back to a generic Home Screen and didn't give me any confirmation of my order. Then I got an email saying there was still an internet plan waiting to be confirmed in my cart. When I try to log in with my Xfinity ID, my phone number, it says that it doesn't match any records. I tried setting up a new account under my email address, which I believe also used to be set up. I have tried resetting passwords, which it does let me do but when I try to look at my account settings or anything it doesn't register that I'm signed in. The Xfinity assistant will not let me speak to any assistant as it says my xfinity id is not valid, when I try to get it to bring me to a sign in screen to try my e-mail address, it just loops over and over. I have tried virtually everything I can and can't even call to get this figured out as they require an Xfinity ID to speak to anyone. I'm going crazy, please help me, I need to get internet set up at my new home asap as I work from home and am dependent on it.
