I would give 5 negative Stars, they almost made me lost my flight, I booked the night before a Max car to go to the airport and the day of the ride, the car did not showed up, they did not send me any communication so I decided to call them and they told me that they have no Max cars available, that they could send 2 Normal sizes cars. No other solution available, so after receiving their confirmation on the night before and called them to reconfirm they came up with this, obviously their confirmation are worthless. Careem is Unprofessional, unreliable, amd I would not recommended at all, avoid by all means.
