We booked a car at (what we thought was ) Europcar through Holiday Autos at LGA in New York. We showed up one day late because there was a mistake in the booking. Yes, there is a no-show policy but we called as soon as we noticed the mistake. Holiday Autos said they tried to reach the Europcar desk at LGA but no one picked up so we should book a new car even though they hadn't even spoken to Europcar (though we'd paid over 200€ for 6 days). We called LGA about 100 times, no one picked up. We rode out to LGA, but Europcar was no where to be seen at the booth, it's run by their partner Advantage, who claim they can't access Europcar customer's reservations and that we needed to call Europcar. We called Europcar, who said they can't access our reservations so we have to call Holiday Autos. At this point, it was late afternoon in the US and apparently the Dublin call center was closed, so we were rerouted to a call center somewhere in the world (NOT Dublin, where Holiday Autos is located) and the call center agent said we had to call Dublin the next day when they were back. All he could do was book us a new car. We called Dublin again the next day and got the SAME exact verbatim script as in the two calls before - we can't reach Europcar, unfortunately there is nothing you can do except make a new rental. THIS ISN'T EASYJET - there isn't just one car sitting in the lot each day! We paid almost 300$ for 6 days and were treated like garbage ontop of not being able to make arrangements for a car for at least part of that time. This was a dehumanizing experience, we will NEVER, EVER deal with Holiday Auto or Europcar again and will make sure to inform friends and family not to bother. This is not how reputable companies treat their customers. We are humans, some of which work very hard for 300$, not walking ATMS!
