Telemarketer robocall scam to get credit card info. The call leaves a voicemail that says "Previously your number was registered with either an online give away or an online retailer. You or a family member who visited one of the website entered your name for a chance to receive 2,500 travel dollars for the fabulous all inclusive resort vacation. Congratulations. Your name was selected today to receive $2500 towards this fabulous 6 day, all Inclusive Resort vacation in beautiful Cancun, Mexico"

Don't fall for the scam, do not press any numbers to tell them your phone number is active, otherwise you can expect a lot more calls you don't want, because they will sell your number to other telemarketers.
