Cheating

I purchased a new display of my cellphone Nokia 6630 which according to shopkeeper was original but within 24 hours it stopped working. wen i went to that shop he said there's no guarantee of the item. If the item is original then how it is possible that it does not lasts even a day. On arguing further he told that it was the display of a cellphone while on the previous day he told that the display was original and brand new. He clearly cheated on me. Please help
