I actually had the same problem, I was so out of it that I confirmed the zip code. I've cancelled my card, but I was hoping you could tell me how you dealt with the problem, since your post was made about a year ago I thought you might be able to help.
This number just called me on my cell that I JUST got a week ago asking for my wife.
They asked, "is this her husband?" When I said yes, they instantly hung up.
Thanks to quick access to the internet while on the phone with these people, I was able to pull up this site and confirm that this is a scam before being a scam victim!!!!
Mom's getting calls from this number on her cell, which is not a number she's given out for anything. They are telling her she's won $125. It's a scam!
