Unhelpful Booking.com

I booked and paid for a holiday in December for my family On Booking.com, having used them before I thought we were safe but to my horror I wake up in the morning (a month later) to see that my booking was canceled. I call Booking.com and try to find out what happened. All I get is “Unfortunately we had to cancel and we cannot help in any way, as Booking.com’s management had already decided” I asked to speak to Managent and all I got was a woman sounding the same as the call center agent telling me the exact same thing and that “maybe you should check our listings “ What would you do if you were in this situation right now? After Covid you would think people are united but they really are just unhelpful, ruthless idiots
