Worst extremely risky experience. I booked a cab for Hyd airport 12 hours in advance, paid advance and got confirmation email, got a driver assigned, driver confirmed that he will come only if paid in cash and I agreed. 10 minutes after pick up time, he stopped picking my calls. Never ever try MMT for airport cabs. I had to seek help from neighbours to drop me. MMT did not even say sorry not even returned the booking amount.
