Flipkart — Titan NQ1805SM03 analog watch

I had recently purchased titan watch using flipkart and the product I received is entirely different. Not only it’s a different item I received, it doesn’t even have titan logo or name on it. I believe it’s a duplicate or fake. I tried several times to return the item to replace and refund, but every single time my return is getting rejected. There’s a return policy of 10 days and I started raising requests from the very day I received and opened the package.
They are simply telling me to wait and then rejecting my request without a proper reason provided.
Please help me get my money back
