MakeMyTrip India — not refunding my money for failed transaction while doing flight booking

Address:

D175, Sector 49, Gautam Buddh Nagar, Uttar Pradesh, 201302

I was booking a ticket from delhi to hyderabad through flipkart on makemytrip. Money got deducted but ticket didn't generated on date 16th and 17th two times. When i chat with the customer service, they told me to wait for 3 days so wait for that much time.. And after 3 days they didn't reply or try to contact.. So i again called them regarding this.. Then they told me to wait for 12 hr to 48 hr again. And after 48 hr also they are not refunding my money and even not trying to contact me.. Its been 10 days now... Still i haven't not received my money. And still they are saying wait for 24 hr to 48 hr. And at the end they are still not refunding nor trying to call me. Please help me about this. They asked for bank account statement
I provided that one also still they didn't refund my money.. I am also working in private sector and i have to take permission to go out and talk with customer care 1 hr since i have say everything from starting whenever i call.. And they are doing fake promise that they will call and inform.. But they are not informing anything... Taking permission in regular interval can cause a job loss for me... And i can't leave 8000 since 8000 matters for me.. Please help me with this.. I'm having all the call records and screenshot.
