Unauthorized Credit Card Charge at BKG Hotel via Booking.com

I received an SMS from QNB Bank at around 00:50 this morning regarding a charge of 258.44 euros made at BKG Hotel on Booking.com with my credit card. I did not make this purchase. I have not shared my card or information with anyone, nor have I lost my card. This transaction is not mine. I request the cancellation of this transaction and compensation for my loss.
