I used Manan Cabs for 3-4 times, but after my last experience I am sure I am never going to trust them or ever use them.
Once I was traveling after 11 in night, there was waiting time of 10 mins, and travel time of 30 mins, God knows with what calculation driver put some package and charged me Rs 700 instead of normal price of Rs 400 , and when I called them they talk very softly, and say they will get back to me, and after 5 times, nobody ever gets back to me.
Ultimately in last call they agreed their mistake and said driver will come to return the money, but after 15 days nobody has come. I am treating it as lesson learned. Never trust these people.
