This company is a sham and a joke. My experience with Rentalcars.com was one of the single worst examples of customer service I have ever endured. I got an email the night before my car pick up that my booking was not confirmed (despite already having a different confirmation email from Rentalcars.com a month prior, and having paid), so I rang customer service. After a 15-minute wait, the person was rude and unhelpful, and couldn't answer a single question. He told me to 'call back at the end of the day', despite it already being 5.30pm. He said call at 8.30pm. When I did, the customer service line was closed, which I can only assume he knew it would be. At 12pm the next day – 30 minutes before I was supposed to pick up my car in Greece – I received an email from them saying my booking had been cancelled. Luckily, I had booked a replacement with a genuinely reputable company, anticipating this would happen. At the call centre, they have a 'policy' that they cannot elevate your complaint to a manager. I imagine this is because there either is no manager, or they get so many complaints that it's an unmanageable workload for a single person. If I could rate my experience a 0 or less, I would. If I hadn't taken the initiative, I would have been stuck at the airport with no car.
