Unable to access Comcast/Xfinity email, stuck in endless link loop

I am unable to access the Comcast/Xfinity email account I've had for years. I see others on this forum posting the same issue and it seems they only get a resolution when someone reaches out to them personally, and I see no options to submit a formal help desk ticket for this particular issue.

Whenever I try to sign in to check this email, I'm taken to the same page here: https://www.xfinity.com/support/articles/account-email-information and directed on that page to log in here: https://connect.xfinity.com/appsuite/ where I'm given a loading page that reads "loading your email", then I'm sent to the main page here: https://www.xfinity.com/hub?cid=cust where I'm directed to click a link leading back to the original webpage. 

This is clearly an issue that others are having; I've tried using other browsers, other devices, clearing my caches on all browsers on all devices, using a third party app for email access, and literally nothing has worked. I only want to log in to this email so I can have it all forwarded elsewhere; it's been my email address for 2FA for years, so I desperately need access to this account to continue logging in to basically every other service. PLEASE send help, this issue is beyond frustrating.
