I kept getting calls from this number and did not answer because I don't recognize the number. They did not leave a message. I finally called it back the other day. I could not understand the name of the company when the person answered the phone. I asked who they were and why they were calling. The guy's response was 'Well, who are you and then I'll tell you.' He was really cocky and I asked again who they are and why the keep calling me. He did not want to tell me and kept asking for my name. He finally said something about a sweepstakes (I haven't entered any). I told him I wasn't interested. Haven't received a call from them again. They were calling 2-3 times a day.

same as message above.  they told me I was the winner of $250 gift card for answering a survey 9-12 months ago.  I said I did not participate in any survey and she quickly said "ok, bye"

All I know is that it comes up on my caller ID as ONYXX. Hope this helps. It actually is a number from Tallmadge, Ohio.

They have been calling my house and hanging up when my answering machine picks up!  very annoying

Called today, said I had won a prize for taking a survey. (I dont take surveys)  All I had to do was let someone demonstrate a tri-star vaccum cleaner.  
 It's a sales call trying to claim it's part of a survey so they can say they're exempt from the National Do Not Call Registry.
