I booked Tempo Traveler with Silicon cabs( http: // https://siliconcabs.in) . They sent the confirmation they did not turned up to pick up. We got to make many phone calls which went unanswered later on when they were not able to speak to the driver and get back to us. Our entire trip which was planned well in advance went for a toss.
So, please be careful when you choose this kind of unprofessional guys. We got to end up paying more money to the other traveler guy as that was a last minute request and also got to loose money for accommodation.
I suggest not to book a cab by using this service provider.
