We booked via Carjet with their partner Fair Car in Iceland. We agreed with the rental company Fair Car in Keflavik Int airport that we would return the car on 11 July between 8:30 and 9:00 in the morning. These are not out-of-the-office hours. We arrived at exactly 8:45 and everything was closed, no one to be seen. We had 2 phone nrs, so we called : no reply, even after 4 min waiting. This is really not acceptable. We were standing in the middle of nowhere with 2 kids, and had our flight to catch. Since we did not know when someone would show up, we had to order a taxi, to bring us to the airport. We are very very disappointed about the service, no one being in the office, and no one answering the phone. I sent a complaint to CarJet, as well as to Fair Car itself, NO reaction from both sides, complete silence. Afterwards, I read many bad reviews on FairCar in Iceland, I can't understand that Carjet continues to work with them. Will never book via Carjet again.
