Yatra.com — Cheating/Pathetic Customers

Hi, I made a reservation online reservation for an international flight & money got deducted from my account then I get a call from yatra executive that your tickets are not booked & I would need to book a new reservation. So I had to go ahead & book a new reservation & then also await for the refund from Yatra which they promised in 5-7 working days. I did this transaction on 25th April & today is 17th May but there is absolutely no clue where the money has gone. Have contacted Yatra & they gave an ARN & Transaction ID & suggested me to go to the bank. I Spoke to Bank customer service & even went to the branch but Bank denied that they have received any money from Yatra .com. This is really frustrating & not sure why it has to take 3 weeks to process ones refund & why do they first have to charge money when they cannot book the reservation & then again made me cancel the reservation & booked a new one. Please help where else I can escalate this matter. Booking reference [protected]
