Website Keeps Logging Me Out

I am moving into a new apartment this weekend, and tried to set up my internet a couple of weeks ago in advance. Today, I tried to make sure everything would be set up before I moved in this weekend, but I noticed no sign of my account being activated. No confirmation email, no charge, or anything. So I tried going through the process of signing in and activating my service again. I walked through the whole process again, but still nothing. I then tried the Xfinity mobile app, but the app tells me that "Access Not Authorized". My wife tried to log in through her device, and it immediately logged her out as well. I am also told that a linked account is unable to make changes, so maybe I have two accounts for the internet as well? I just want to make sure that my internet is going to function when we are fully moved in next week, and that I am not going to be double-charged on my card. The website continues to log me out before I am unable to perform anything in the settings to try to clear things out myself. I have a confirmation email that my XfinityID was created, but no confirmation email that I have services starting this week.
