It's from RCI (Blue Green) Resorts.... It's a timeshare promotional company offering deep discounts on VIP vacation options to various locations including Aruba, Las Vegas and Orlando..... It's just telemarketing for people who may have previously gone to one of their locations. If you do pick up the phone or call them back, demand that they remove you from their calling list and ask them to read back your number so that they don't just tell you that they are removing you, but are really removing your number from their calling list. Don't be surprised to get other calls from them until your number is completely flushed out of their system.
