This is some type of "Free Vacation" scam.  First they sent me a text, telling me, "I won", then a few days later, when I didn't reply to the text, I received two phone calls from the above phone number.  The first call, I did not answer and no voicemail message was left, they just hung up.  The second call just a few hours after the first, also was unanswered on my part, but they did leave a voicemail message, asking me to call back to confirm my "award".  I did not hear the complete company name, as the person who left the voicemail message spoke VERY fast, and I automatically deleted the message after I listened to it.   I have now blocked their phone number.
