I got a call from that number too, but in the caller ID it shows it as Security HM WCA. When I answered I was met with a recording that I had entered their sweepstakes on walmart.com or some other retailer website to win a free security system. I never personally did so, but assumed maybe someone else in my household did, although it's unusual because we have a security system in place already.

when i pressed 1 to speak to someone, the required my first name and last name before allowing me to continue or to even find out how they got my information.

Shady...and I feel its definitely a scam!! Also a google search shows many people with the same issue.

Well, it's still calling...me an hour ago. Heard a beep while I was in the line with a sick relative and hurried off to answer this call, hung up b4 I could answer and did not leave a msg. Scumbags.

Not only received a call from this number I also received a text that said please call...

I just got a call from them too. on my cell phone. no msg either. that is annoying.

I just got a call from this number too.  In fact, they've called me several times and it's a recording stating that I was entered into a Walmart Sweepstakes.  But if I don't answer, it does not leave voice mail.  I have requested to be placed on the no call list but apparently it hasn't gone into effect yet.
