Address:

Randhawapuram ,BSF Academy, Tekanpur, Gwalior, Gwalior, Madhya Pradesh, 475005

I had made a transaction (Amount: rs.6, 987) on 4th oct 2018 for the flight booking through upi payment gateway and complaint this case many times but didn't get my amount. They only give time that u will get your refund in these many days but didn't get. Actually when i was booking for flight through upi, it was successfully transacted and amount got deducted but flight booking was not done. So, please i request you to please refund my amount which i had got deducted from my bank account.
