Myntra.com — Order not placed but money is debited

I ordered roadster jacket yesterday and paid from Google pay but after payment done, it showed that you order is not placed but you money is debited which will refund soon to you bank account...but money is not refunded till now and also that jacket had 60% discount and now it had only 45% ...so this is big loss for me ...now I have to pay 600 rs. Extra for that jacket..
