Getmecab — Changed car, lied about the substitute car's condition

I booked a sedan car (indigo petrol @₹14/km) from delhi to nainital. got a call 7 hours before that they can only send indica @₹13/km. they claimed it's a brand new 1.5 months old car. i accepted. but the car that arrived was the worst conditioned indica i've ever seen, and that too gas operated. there is dust everywhere. so unprofessional and disappointing service by getmecab. never gonna try it again or any other associated company.
