Started a new account, picked a new plan, verified my email but can't log in to my account.

I picked out a new plan, made an account, and picked a date for installation. Then I verified my email but every time I try to log in to xfinity.com it accepts my log in and just takes me back to home page and signs me out. I've reset cache and cookies, tried various devices, tried the app, and reset my password but no luck. I also called customer service and they couldn't so anything, I need internet ASAP but can't log on to set it up. Is there anyone recourse here?
