Fake product

I ordered 3 kurtis worth 1500/- from Nattashi.in n they did not respond till now …n they do not have any contact numbers…at last I got this phone number 8249406219 under Rahul Dharma n he’s asking bank details like card num…expiry date n cvv…so definitely this is fraudster who has opened this website n cheating customers…pls take legal action on him n on this fake website
