Abbots Cove BnB Did Not Exist

A rating of one is too much. We booked at Abbots Cove, Hilton in June 2021 for May 2022. On arrival we found the establishment had been converted to a children’s boarding school. Booking.com failed to notify us of this change, accept absolutely no responsibility - & the cherry on the top request that we submit a review so the establishment can in make improvements. What part does Booking.com not get? the BnB does not exist.
