Flipkart - Fraud by delivering wrong mobile

Ordered Samsung Galaxy A* (Black, *** GB) (*GB RAM). Order Id OD****************** Made online payment by internet banking for the amount of Rs.**,***. Instead of delivering above mobile they delivered Redmi mobile with a broken display in the Samsung Galaxy A* box. Logged * times return request with them for refund of amount mentioned above. But each time they rejected request stating that the reason for return is not correct. My complaint is that fraud has happened at their end before the product reached me. I am very upset and frustrated by the way they are not accepting their gross mistake. It looks that the company is totally bogus and customers should think many times before something like this happens to them. I have lost so much of time and money. And now I am left with nothing. This is seriously back stabbing me.
