Paytm Mobile Solutions — Amount debited but not refunded for paytm movies

I tried booking tickets for movie on Paytm. It debited the money (Rs.1977)from my Paytm wallet but the tickets never got confirmed and it said the money would be refunded to your account within 24 hours. Fast forward more than 4 days, there is no reply from the paytm customer care service and on twitter for the past 2 days all they are saying is that "Your concern is important for us. we are looking into it.
