Better than I did. I got a call from "Visa" about a decade ago telling me that hackers could break "the codes" used to protect my credit card. I played dumb and gave him a card number (first 16 digits of pi) and we ended the call. I just a bunch of callbacks that I refused to answer several minutes later. I was still on dial-up and I don't think any of my credit cards offered virtual numbers at that point, but I should have set up a card with a $0.00 or $0.01 limit and given that to him, and then sicced fraud services on 'em.
