Booking.Com is the worst!!!

I own property in a Nature Reserve that was temporarily closed to visitors due to disastrous fires and water and electricity infrastructure damage. I sent Booking.com emails to inform them about the situation and to ask them to cancel the relevant bookings because I did not have guests' contact details. (which I also requested, but to no avail). I phoned them numerous times and asked them to assist me with the cancellation, and the only response that I got every time after my call was an e-mail stating that I must communicate via the online platform - which I did numerous times. Booking.com is the worst platform for guest house owners - poor assistance, poor communication, and no protection for the owner of an establishment. Call center agents - if you can get hold of them are clueless!
