Dear Deepti,
You should have verified with the seller befor bidding, and asked him/her the details as the model and year of manfacturing and so on.
Since you have won the bid you are duty bound to pay the seller, I know it hurts but this is the honest way.
Next time be more careful and get the details from the seller before bidding. Remeber all that glitters is not gold, and never go for stuff which is cheap, always ask yourself, "Why is the seller is selling the product so cheap" I wish you all the best and success next time.
