Company calls, leaves message saying they're ADI (Caller ID said Unknown, Fullerton, CA) and need to serve subpoena for employment records. Made no sense as we're small firm. They called again and I spoke with the woman who says she looking for a company called "Savers", which of course is not us and when she asks for our company name I tell her we don't want to be confused with this "Savers" company and that she has a wrong number.  This was definitely a phishing expedition.
