To get back your cheated amount if paid through your credit card you need to raise a dispute request on the credit card transaction you have made to pay for your travel to TRAVELCHACHA and you have a chance of getting back your money.
I got back my flight ticket amount of Rs5052 through Standard Chartered because I used their credit card after almost 45 days and they will forfeit the amount from TravelChacha’s Bank account where it was paid.
I think this is the best way to recover your cheated amount only if you have paid through a Credit Card.
