Phone Scam?

I got a very interesting (and particularly concerning) call on my cell phone on Saturday. Carley and I were at a Wal-Mart in Brampton, when my cell phone rang. Of course, I assumed it was either Ben or my parents (really, who else calls?), but, instead it was someone asking if I spoke French (to which I answered "A bit"). At first, I thought it was Goat as the connection wasn't great and I figured that if it wasn't one of the previous options and I was with Carley, it couldn't be anyone else. But no, the mystery caller went on to tell me that he was talking to a woman who only spoke French and he needed me to translate (which my "uh...sort of" knowledge of French would obviously be an asset to). So, he told me he would call back and we'd have a three-way conference call together. He then asked my name, and introduced himself and hung up. I turned my phone off after this. I have a strange feeling that if I had accepted that call, that my phone bill would be through the roof.

This was most likely a scam of some sort, so anyone else may want to watch out (although I would assume that no one would be dumb enough to accept the mysterious conference call from the suspicious person who strangely got your cell phone number out of thin air).
