No cashback recieved. LOST My Rs.100!

While I was transacting in PAYTM, I Saw an ad in there,
Which directed me to a link – http://paytm.fnp.com/product/paytm/?utm_source=affiliate&utm_medium=Banner&utm_campaign=vcommission

Here it says that PAY Rs.100 from PAYTM Cash and get Rs.105 CASHBACK within 24hrs.
