A person claiming to be from HDFC reached out to me to process my credit card. I asked for the Regalia, and he said he can get it to me LTF (no strings attached), however he said he needs me to share my documents over WhatsApp. I asked him to mail me that the card will be LTF from his official mail, but he said it's not possible because of some backend limitations. I'm wondering if it's legit. Anyone else got a card by this procedure?
