Reduce your credit card rate! Scammers collecting personal info. Hang up....

Said getting a 6% interest rate on my credit cards.  I asked what is the name of my credit card?  She said she didn't know.  I said if they're giving me the lower interest rate, how do you not know the name of my credit card?  She hung up.  Knew it was a scam from the start.  Just wanted to see how far it would go before she hung up.
