Forced password reset every 3-4 days

For about 3 weeks now, like clockwork, every 3-4 days (usually around the same time) I get 2 emails from Xfinity ([Edited: "Personal Information"]). They come at the same time. One says "Please reset your Xfinity Password" and the other says "Your password is all set" (despite the fact that I've taken no action at that point). I've already confirmed the emails are legit and sent from Comcast. Even if I click nothing in the emails, if I go to my Xfinity App after getting those emails, I'm automatically logged out with a message "Your account has been suspended. Please try again later." If I try to sign on through the web, I'm forced to reset my password. I'll reset my password and then this cycle with repeat over and over every 3-4 days with no end in sight. 

I've called comcast close to 15 times now with no solution. I tried changing my email address and now the same problem is happening on the new email address as well. No one is trying to hack my account as I have 2 Factor set up and at no point have I received a random 2nd factor request (which would indicate someone was trying to get in). And when I look at recent logins, they're only me. I get told it'll be escalated and that I'll get a call, and that never happens. It's maddening to have to reset your password every 3-4 days indefinitely for no explainable reason.

I've have spent hours on the phone explaining this over and over again with no help. They've tried on their end "intentionally compromising my account" I guess to do some type of reset. But even after I choose a new password after that, the same problem with happen 3-4 days later. Even worse is I found this same type of problem on messages boards going back years where some people said they literally have to change their password multiple times a week for years straight due to no solution. I'm not willing to do that.
