Failure!
Drivers are so kind. However customer services are terrible. They charged me extra money for my trip because of a technical problem, I immediately call them; after waiting for 14 minutes the customer replied me that refund is impossible. I reached via e-mail, they sent me an e-mail which is beside the point (i guess it was an automatic mail). In the end, I couldnt retake my money.
