Can't Log In (loop)

I made an account yesterday while I was doing the build a plan option on the Xfinity.com website, but when I got to the end of the build a plan and tried to confirm the order it didn't go through and logged me out. Now for the past day I haven't been able to log into the account despite clearing my cache and cookies, trying an incognito tab, trying different browsers, and trying to log in on my phone. Every time I try to log in it just logs me out again.
