Cleartrip — Refund of Flexifly and Refund of failed transaction

My trip id with Cleartrip is[protected], I was trying to reschedule my ticket on their app, they have scheme called Flexifly where they refund Rs 3000 if you reschedule your ticket basically “reschedule for free” scheme, I tried on their app and my bank Ac was debited with Rs 3501 on 3rd October but no ticket was generated, now they say it’s failed transaction but my bank confirmed that it was successful under the transaction id 70001054, now they are not returning my money, neither they are giving me a refund of the original ticket, in total they owe me Rs 6501, they lie and never return their calls and that too they callback once after emailing them 100s of times, I am sick and tired of dealing with them since past 3 weeks, they do not even have a direct email id or phone number, their reviews on twitter and google is filled with such complaints, strict action needs to be taken oresle they will keep looting customers.

Please advise what help you can provide.
