Booking.com are running fraudulently.

They associate with auto union who will fail to make you aware a credit card is required to book (Amex not accepted). At that point they will attempt to charge you €740 up front on a debit card. Full excess +fee

You will be provided no means of cancellation by auto union or booking.com so you either lose your deposit or you lose it all.

We are seeking legal action.

#bookingcom has failed to provide adequate means to cancel. Do not use them
