My account is no longer active... but I was still able to pay my bill.

So I missed a payment by a couple days because I replaced the card that I use for auto payments a while ago. So I forgot to change it to my current new card. So I realized I needed to pay my Xfinity bill, so I paid it and tried changing my accounts payment method to my bank account instead of card so I wouldn't have to worry about that happening anymore but it didn't let me. I was prompted with a "Restricted section" message when I tried changing my auto payment method. My wifi was down so I had to buy the Xfinity Now pass to be able to use Internet. So I checked my bank account to see it the payment went through and maybe it was just processing. Checked it and it went though so I checked the app to see if it was maybe an outage but I got hit with a "You no longer have Xfinity service" message. So I reset the WiFi box to see if maybe u had to reset it back to it's default settings to get it up and running again. That didn't work. So I checked my actual account to see if maybe something happened that I didn't know about. My Xfinity email inbox had an email that said I had to pay my bill to get the Internet up and running again, after that one was another email that said that my payment went through. So I was confused why nothing was working. I than checked the account and identity section on the website and it said that "This account is no longer active" so now I'm stuck and don't know what to do. I didn't know missing a single payment by a couple days would cause this much issues. I already paid for the Xfinity NOW service just to even get online.
