Flipkart — FAKE casio watch delivered(CASIO G-SHOCK GM-2100-ADR)

I ordered a casio gm-2100-1adr g-shock watch for 11, 805 at flipkart from seller retailnet. However the watch has turned out to be fake as the watch hours and minute hands are stuck and i thought since this is under warranty i'll get it fixed. However, while registering for warranty i couldn't find the watch serial number at the back of the watch which is required for registering the watch for warranty. I got the watch checked at casio store which confirmed it's a fake watch, with obvious signs such as no serial number, spelling mistake in the back engraving which does not happen with the premium casio g-shock watch. Now i'm stuck with a watch which is not working within weeks of delivery and can't avail warranty since the watch is fake even though i have an invoice a warranty card the watch box and everything.
Please refund my money and collect the fake watch back (Along with the box.
