Unable to Pick Up Rental Car Booked via Booking.com, Requesting Refund

I rented a car through Booking.com to pick up at Germany’s Cologne/Bonn Airport, but upon arrival, I was unable to collect the vehicle due to an issue at the rental location. This left me with no choice but to rent another car on the spot, resulting in an additional payment at the pickup location.

Since I couldn’t use the car I originally booked through Booking.com, I am requesting a full refund for the amount charged. This situation caused unnecessary inconvenience and extra expenses, which could have been avoided with better coordination.

I expect Booking.com to process my refund promptly and provide better support to prevent such issues for future customers.
