Paytm Mobile Solutions — your bank hasn't confirmed this payment

I received a cash back from playing a game. It says that payment failed due to bank hasn't confirmed it. I want to check my status and wanted to know what i can do to get this done. I also didn't get the cash back for "rangasthalam" coupon code. I booked a movie ticket using "rangasthalam" coupon code but didn't receive any cash back as u said that they will be a 100rs cash back.
