Let me be very clear, because it seems that folks are fixated on AI and believe it is in more places then it is. The responses you have received have been from actual real life people, we do not use AI to reply to tickets.
It does look like there was some confusion because of your used of “warband”, as they did relate that to the Warband’s warbank. The trouble also is, we’re not seeing any clear sign of compromise. You have an Authenticator on the account and it doesn’t appear it was removed at any point.
I see you have a couple of other tickets open, and one specifically in the compromise queue, so hopefully we can take a closer look at it.
