Triviyaa — wrong product received or not refunding when asked

I have ordered a lehenga (Order no 188631) in triviyaa.com (Under fablulous) and were delivered on 28th may 2018. Unfortunately the delivered products was not what i ordered.
i called on ([protected]), sonu kumar, when i asked for refund he asked my debit card details, and then cvv, when i refused, he said -i will not refund any money to u. and after 2 minutes i got some OTP on my no,
this is a clear case of cyber crime. and my money is also not refunded.
please return the money or i will take some action against it.
