I called it back and the message advise that I had won a free prepaid card. It wanted me to give my information. NOT A CHANCE!!!! So you can try it, but I am not going to do it.
Good luck getting free anything in this day. EVERYTHING has a price... Is it your personnel information??? its just a phone call away. hahaha I wouldn't call it back. Just do like I do. log into your cell phone account and block the number for 90 days.
Hope this help someone else.
