I got a call from a peron stating that he was calling me from HDFC credit card department that they are offering me a free gift as i had good reward/goodies points in my HDFC credit card. The asked me for all my credit card information and later on redirect me to GoIndia Buyer to and purchased a product of Rs 16999. There was no way I could reject the order and this is a fraud that they regularly do.

I already informed my bank HDFC for same . I would like to file a complain against Go India Buyer for doing fraud. There are many such complaints against them:
