I have an advice for the customers; please do not reply on GTS car. They are very unreliable. I booked a cab a week before and an hour before leaving, the guy informed me he cannot provide me a car from Dehradun to Delhi, and when I told him that it is very inconvenient; he replied that he does not care and I should find a solution myself. I have a flight in the morning. Please do not reply on their service.
