The booking site is your agent in this and when things go south they’re there to help remedy the situation. They should have been your second call right after the first call to the property when you arrived. For no other reason than to document the service failure.
A similiar situation happened with me on a booking.com serviced apartment reservation and they were able to get in contact with the agent who took me to dinner as an apology. Your intentions were good and understandable but in today’s age communication is literally in our hand everywhere we go. I can definitely understand not wanting to stay there but if this happens in the future either negotiate the refund then or some other form of reaccommodation with them.
you can try a chargeback and may get lucky.
