Booking.com false accommodation

Good day, We made bookings for accommodation in Egypt via booking.com we arrived 4am the morning to a hotel that does not exist. We then had to pay for a new hotel because booking.com just did not return and still now we can't get our money back. We have been sending mails to them now for more than a month with no luck. How will we get our money back. And not just the money you travel to a country you do not know with a booking you thought is from a trusted source but clearly not. They have made the mistake now we must suffer the consequences. How can I go about to get this matter resolved and to ensure places like this don't get booked.
