Website:	paytm or indigo ailines or sbi bank i dont know for real

I have made a flight ticket booking recently via paytm app using bhim upi on 29th april 2018 . the ticket wasnt confirmed as the airlines claimed they have not recieved mone.i had to book another ticket for same flight from airport by paying more money than to what i confirmed while booking.So if money havent reached the airlines.but debited from my account, why isnt refund initiated yet? calling sbi says to call paytm and calling paytm says call sbi to get this issue resolved.am stuck . who do i ask my money back then?am facing financial issues now and want you to solve this soonest. please .
