I called the number back. This was a call center supposedly out of Florida. They wanted my credit card to charge $4 for shipping so they could send me out coupons, gas vouchers, and a $25 prepaid mastercard. Said they got my information because of an online purchase I made.... I haven't made an online purchase in over a year. Might be legit...might not. I didn't take any chances and hung up. But not until after they got my name and year of birth. May have gotten scammed without even knowing. We will see.
