I apparently won a trip to Cancune from this number but because I wasn't 25 y/o I could redeem my winnings. I have a feeling it may be a scam, the women was not very helpful and even waited 45 secs for me to hang up after she told me I wasn't eligible. I turn 25 next month and she had prompted me to call back when I am of age (offers like that don't wait for you) so I asked her for a number to call. She replied with a cold "don't you have the number on your caller ID" and sounded like she was working in a news-room in the background.
The most alarming part of this that googling the number took me straight here. Normally, if it were a real company, I would have been directed to their promotional website. I wouldn't trust this call.
I've received several calls from this number on my cell phone and I'm not sure why because I use my cell phone to make phone calls only. Anyway, I called the number from my office phone to see what would happen, I was going to ream the person for calling my cell phone. On comes a recording. It provides you with an option to have your phone number removed (it'll take them 7-10 days for this process).
