If anyone here wonders how scammers make any money, they don't need to read further than this thread. The mere fact that someone posts here to ask whether it might be legitimate, given that if one had such a suspicion, UA has published numbers one may call in both the US and Mexico, points to the fact that there are some who would actually return the call here, provide their CC number and wind up spending months getting a new card, cleaning up their ID and hopefully getting their credit back to close to where it was.
