Ibibo Group / Goibibo — Flight booking

Address: Gurgaon, Haryana

I booked a ticket from new Delhi to Bangalore on 14th february through goibibo, my amount was deducted and booking was not confirmed, so i contacted their customer care executive and they told me that we(goibibo) didn't get any money and no seat is booked.so i booked another ticket and what they guys did, they booked two tickets for me one from previous amount and one from another transaction.i have already called more than 15 times and i am not getting any satisfactory answer from them, and they are telling me that they will check call recordings and will contact me nothing has been done yetand they have refunded only 1336 rupees.i need my whole amount to be refunded.i know my rights, this is fault from their side.So i need help from you guys so that i can get my whole amount refunded.
Thanks
