I have been getting multiple calls from this number as well, calls my cell at least twice a day. It is apparently a cruise line. No idea. I blocked them today when i called back and heard an automated voice message from Jennifer.
Caribean Cruise Lines offering a free cruise within 18 months. You have to pay $59 per guest (2 required) per day. So they want to charge $600 to a debit or major credit card.
