> how do you imagine did they get the information needed to call you back and knew of the booking?

Maybe booking.com sends an email to the hotel, but they legitimately don't have the login credentials to cancel the reservation?

There's 0% chance this is what happened. Hotels can get in touch with booking easily by phone or e-mail to fix any login issues, or to delist from booking if they don't want to be partners. Also, why would they have to log in? Booking.com sends their invoices by e-mail as well.

This case was commission fraud by the hotel against booking.com

Had this. That was exactly what happened to me. It was refunded and I decided never to use booking.com ever again.

Good choice, for several reasons.

IIRC when I worked at booking until 2017, they had already stopped the practice to share customer data via email for privacy+security reasons years ago.

This was it. They add calendar events too apparently.
