I have bought a Sony Bravia - SONY-LCD KLV-32BX300 in the month of October 2010. They have given me 3 gift coupons (Scratch Card). As per instruction I have sent the coupon no. to the specified no. vis SMS.
Later I came to know as they confirmed that I have won the 3rd prize of a Digital Camera. As per their instruction I have sent all the relevent documents except the original Coupans which were lost by me.
Now they are saying that as I have not sent the original gift coupans my gift has been cancelled.
Is it fair as I have the bill of purchase and have sufficient evidence of my identity ?? My name was also displayed in their official website. I am planning to go to consumer forum.
