They called asking if I would like to lower my interest rate on my Chase credit card. But then asked me for my credit card number to make sure I didn't loose or shred the card. I asked, "So if my dog ate my card and you needed to send me a new one I couldn't qualify for the interest rate I have to give you permission to lower?" THEY HANG UP. I called Chase they confirmed it was a fraudulent call. They would never ask.
