Xfinity mobile app/website not showing correcr services, plan or modem

Good morning,

I was given a new xfinity gateway modem yesterday at my local xfinity store to replace an old one. We also updated my plan to have higher internet speeds. Since yesterday, the xfinity mobile app and website does not show the correct plan/services. In fact, it shows that I do not have internet or a modem at all and instead shows that I have flex and voice - which I absolutely do not. This is extremely concerning and I want this fixed as soon as possible. I am unable to make my internet secure or finish updating my settings. Please contact me as soon as possible with a resolution.
