[Resolved]  MakeMyTrip India — air ticket cancellation amount not refunded

I have booked return international return ticket from ahmedabad to dfw usa in the name of mrs. Manisha shah on 15/05/2017 vide booking reference no. Tlvqad form maninagar, ahmedabad. Contact person mr. Veenit chauhan.
Due to my some personal reason on 03/06/2017 i inform mr. Chauhan to cancelled my return ticket and accordingly he said that amount of cancelation refunded in a week in your account.
More than 57 days are passed but yet amount is not credited in my account, i taken so many frequent follow up by email, whatts app messages and phone call fro usa.
Pl inform me why should be delayed?
Why should i am not claim for interest & harassment charges there on?
Its shocking, harrowing and insensitive, i have completely lost faith from make my trip, all this has left me with a bitter experience with a renowned travel agent.
