I was using makemytrip till 2016 but after that I started using Goibibo instead.
My experience of using Makemytrip has not been good as I had faced difficulty in applying Gift card of MMT on its website for 3 consecutive days. At the end, I had to pay money from my credit card to book the deal.
When I contacted the Support team, they said it is a minor glitch in their system and it will be rectified soon. But it was never untill the 4th day.
Then the gift card was of no use to me and I decided to give it back to makemytrip but hey refused to take it back.
Also they did not provdiie any coupn code to me a token of courtesy for the issue in their system.
Overall, it is a very bad site in terms of support and customer care.
