I got the same phone call yesterday. It was a guy claiming to be a cousin stuck at Mexicali customs, and needed money to get all his money and stuff back. He knew the city where I lived, but not the address. A lady was also on the phone claiming to be a Mexico customs agent. Turned out to be total BS because I later called all my aunts and uncles in Mexico to verify if any of my cousins were traveling. They all said no. Half an hour later, the same guy calls asking if I wired the money via Money Gram. I told him that his brother (my other cousin) was here and that he wanted to speak to him before we sent anything. He hung up and never called back. Scum bags!
