Radisson Hotels & Resorts complaint: Fraudulent Activity

I joined Radisson Rewards in November, verified the account but for various reasons I did not use the hotel I created the account for,
On Friday night it seems someone has hacked my rewards account and booked hotel using my contact details (fortunately they appear to have guaranteed the booking with a card that is not mine) I’ve contacted the hotel, was passed to reservations team who told me to contact the hotel. Customer services on Saturday told me they do not have a fraud team but someone would call me back. Customer services today said they would escalate the rewards card fraud but can nit tell me if or when someone could contact me. Told me to call the hotel about cancelling the booking I did not make.
e-mailed customer services who replied with we are sorry to hear about your poor experience at your recent stay
Contacted Police Scotland but as the fraud has not yet been ‘completed’ they can not assist
The last thing I have done is e-mail the hotel (although it seems like a funny e-mail address) and said they can do what they wish with the booking but if the card declines I accept no responsibility. Don’t know what else to do – absolute abysmal company
