New Customer Checkout Process Failure, Unsure how to proceed.

I'm a new customer attempting to set up service at a new construction.

I built a plan, entered payment information, and got all the way to the final step of checkout. When I attempted to submit the order, the page stopped responding and then timed out. I never received an email confirming my order or saw a page confirming that the order had completed.

Thinking the checkout failed, I attempted to start the checkout process from the beginning a second time. When I got to the step asking me to create an ID, I chose the login option and entered the ID I created on the first attempt. I immediately received an email informing me that a second account had been linked to my Xfinity ID. I did not proceed any further with the second checkout attempt.

If I try to log into Xfinity, I get booted back to the homepage, and when I try to click any of the account options on the breakout menu I get met with an infinite loading screen.

I am unsure how to proceed, because the email I received seems to indicate that an account exists within the system, but I don't seem to have any way of logging in and viewing it.
