MakeMyTrip India — Overcharged for ticket

Address:	Gurgaon, Haryana
Website:	MakeMytrip

I purchased a business class ticket from an agent at Make My Trip and he quoted me a price after booking the itinerary. After paying the agreed amount, he called me and told me that one of the flights in the itinerary was not available in business class and helped me find another flight after which he told me that I had to pay an additional Rs 38, 038 which I paid. I then find out from the airline website that the price was at least Rs 45, 000 less than what I paid and I have been trying to get them to send me a detailed invoice for the ticket. They do not want to be truthful that they charged me around Rs 45, 000 service fee for the ticket. When asked for a supervisor they would not transfer my call and my calls have not been resulted in any resolution.
