Free cancelation

My property sthalas @ mahabalipuram India , have received 16 reservations during December 2023 as free cancelation, inspite   of prepayment   condition, only 2 guests turned rest 14 guests neither responds to messages or calls nor made prepayments and no-shows, resulting heavy loss to the property owners.

Booking.com to take concern to help the partners to collect payment from guests before reservation.
