I have two bad experiences with Careem which i like to share, first time was in Kuwait, i requested "economy" car, they send me Toyota Corolla, then later on the day i thought that i might need a bigger car so i requested business car ...... they send me the same car "Toyota Corolla" and charged me higher fare ... then when I complained they said that Corolla is considered luxury car !!!
The second case even worse ... i booked a driver ... then 10 min before he arrives he called me saying that he has a flat tyre and i should cancel the booking and make another one ..... Careem charged me cancellation fees before i cancelled two hours before the pickup time!!! and until now am waiting for their costumer service to update me ...
