This cab service agent is a big time fraud. His business is running on random catch "tukka" and by fooling and looting people. He will take the advance, will not pay to cab owner and cab owners who are good alliance with him will extort money in full. And this guy, calcabz will never return your advance. If anyone takes service from him, he/she might even have to go to police station, though he had the audacity to defy law and order too.
Once I posted my experience with this guy, he asked me remove my review saying he will make refund post that. But he doesn't do that also. And eventually he will stop taking your call.
Be careful!
