i received a call and they said tha "a security hold has been placed on my mmastercard" When I call the number a recording  says "thank you for calling the murrayhill center."

 confusing.

Got a call on my cell phone saying my mastercard had a security hold and asking me to press "1" I call my only mastercard and it has no security hold on it. Total scam.

I got a message saying a security hold had been placed on my Mastercard and to press "1".  I called my Mastercard directly and no security hold was placed.  This is a scam!

Got a call stating they wanted to invite me to a focus group on Weight Watchers, and that I would receive $100.  Then they started to ask too many questions.  I started to feel uncomfortable so I hung up.
