Hi. I wonder if anyone could help.

I booked a car online at holidayautos.com to pick up for a car rental station in Berlin / Germany.
Unfortunately, our Easyjet flight from Manchester had 1.45 hrs delay and landed in Berlin after midnight.
The car rental station closed at 11.30pm.
We contacted by phone the car rental company in before from Manchester, as soon as we noticed that the flight may be delayed. We told them about the problem, and provided our flight number. They advised us on the phone, that we can pickup the car the next morning, and that they will send a fax to the car rental station, to let them know.
We had to book a hotel for the night, to be able to do this so.

Next morning I called the car rental station at the airport to inform them, that we will come over to pickup the car, but they just informed us, that the car is gone, as they just keep it for an hour, which was before midnight the day before, and that they don't have any other car available, nor will refund the money.

We had to book another car with another car rental station to be able to go on with our trip.

Holidayautos.com, where we booked the car online, is not willing to refund the money, even there was no clear notice, that the car can only be picked up within one hour after the reservation, which they told us at the car rental station first.

Easyjet does not compensate us as well for the car nor the hotel.

I wonder how it can be legal to collect money twice for the same car?
What can I do in this case, please?

Thank you in advance.
Kind regards
Manfred
