2 years ago, 4 families bought apartments through Booking.com in the same location and time in Greece. The fee was charged in advance (January) to be cheaper. A month before departure, booking.com canceled all reservations (July) because the facility became unreliable according to them. Of course, the flights have already been booked and paid for. As it turned out, bookking.com transferred the money to the facility's account and the facility broke off the market. Booking washes hands, does not want to return the cash and sends you back to the facility that no longer exists. We quickly found other objects matching the tickets we had bought. We all filed our Charge-back complaints with banks. Some of them recovered their money after 2 weeks, I had to fight the bank for 3 months. Remember, the "charge back" has VISA and MsterCard, whether it is a credit card or a pre-summer card. Even Revoult returned the money in a month. Since then, the fee at bookin.com ONLY FOR A LOCATION, I will never give my card there again.
