Paytm — Money taken by Paytm and then reflects nowhere

Address:

Anand, Gujarat

Hello, I added Rs. 400 in Cash wallet for getting cash back of 40 Rs as per offer. It showed that money was successfully transferred but there is neither 400 in wallet nor 40 Rs cash back. Where has the money gone? I has been more than 12 days now. Please don't promise to reply within 72 hours if your words have no value. Or is this a way of compensating for all those discounts on offer?
