There's a Marriott Hotel Scam going around and they are aware of it. The phone number will actually show up as a local number. My call came from Costa Rica. Costa Rica area code is 11506. If the phone number is different than 11506-328-1940 you should call the RCMP at 1-888-495-8501. They are trying hard to catch these guys.
They callers told me that I won a vacation package to Mexico and they wanted my credit card number. As soon as they asked me for a credit card I new if was a scam.
