Spring Breakers stole my card and got a room

They booked it through booking.com I got a message from my cc through text message that there was weird activity. I called the hotel and they said it was a pre-booking therefore I’m not charged until I check in. I cancelled the room but can not get in contact with booking because I do not know the confirmation number(ugh duh) but I cancelled the card. Will I still get charged?? ??Though the card is cancelled. I cancelled all my other cards also.
