I made genioun mistake and booked the wrong airport. So we made a second booking to the right airport, as our booking was for 4 am, and their customer service line is unfortunately not covering customers 24 hours a day although the bookings are. When I spoke to their customer service agent the response was that they appreciate it was a human error but they couldn't refund the wrong booking because the car park is strict. Holiday Extras you are the agent selling the service, and you have not taken ownership, and tried to use human approach to resolve a human error, instead you pass the buck, ignore your customer, and show no empathy whatsoever. I would recommend you avoid Holiday Extras, they may not be beaten on price, but for service you don't even get what you pay for.
