HDFC discount fraud card

Today I got a call from VISA Mastercards card department. The number was a mobile number from Delhi. But the modus operandi was similar. The told me that I am using my credit card reliably for a long time so I have been selected as a VIP customer of HDFC. They are offering me 5 gifts and promotions.
First question I asked them was how will he prove that you are calling from VISA or mastercard. He said that his is not a fraud as he will not ask me for my credit card information or anything. So, I thought if he is not going to ask me for my credit card information then there is no harm in talking to him. Then he asked me to tell the color in which the VISA/Mastercard logo was made for verification that he is talking to the right person. I told him that. Then he told me that they will send a gift hamper from Axe (the deo company). That hamper contains a leather belt and a wrist watch and is worth Rs 4000. Then the second benefit was a VIP card from VISA which will give me 30% discount on various purchases for one year and the third and the most important benefit was a holiday voucher magica korea worth Rs 60000 to 70000. But as an esteemed customer they are giving it away to me for 7999 which will be cut automatically from credit card automatically and will reflect on the next statement. He asked me to put card details on IVR, I simply refused.Then he said that if you want you can cancel the offer anytime and all. But he called me again after half an hour or so. Then he sent me link (www.auraseven.com). There I smelled a scam and started searching for fraud for any of these. Luckily I found fraud by auraseven. . This time I didn’t pick up the call. Numbers used for call were Dinesh goswami 9350417815 from delhi , Puneet sharma 42455210 from pune.
