The worst rental car experience I've ever had. I have rented many cars for both personal and business travel over the years, and while I've had some issues, never have I been treated like this. I rented a car a few weeks back for pick-up at Calgary, AB. We had a direct flight from Ottawa booked, however there was an overnight snow storm which messed up our flight departure time and rerouted us through 2 other cities before getting us to Calgary. I tried calling the ZOOM rental car location once this all started happening. This was within business hours and before our designated pick-up time, but no one answered the phone. I tried calling again once again from our second flight just before take-off and finally reached them and told them we were going to be late arriving. They were brutally rude and said they had already cancelled our reservation, wouldn't help rebook it and told us to take it up with Holiday Autos, whom we originally booked through. So I tried communicating twice through live chats with Holiday Autos. I'd only get so far and then these would simply just discontinue. I then sent an email with proof of our flight cancellations and changes. I got no response. A few days later I called their UK office (at my expense) and got a customer service agent. She was able so find the reservation and record of the chat conversations and our attempt to contact them in good faith while en route during a very delayed and frankly rather traumatic trip. Even with these circumstances and all the day of correspondence, I was told in a reading from a script robotic way that they would not refund any of the fee that we had prepaid at the time of booking. Nothing. So they've kept nearly $400, despite things being completely out of our control and all our effort to reach out to them. I would highly recommend not booking through Holiday Autos. There are so many other reasonably priced options that don't take all your money up front, or fail so miserably at customer service and even basic compassion.
