ACS Incorporation Threats of criminal action, but sent me a copy of the exact same email as others, including balance, etc. Internet

OMG, these people seem to be sending out the exact same email to everyone with a few of the  details changed.  It scared me quite a bit when they threatened me with criminal prosecution, until I noticed that they were sending the "notice" from a gmail email address, & the phone number is preceded by a "1", as in 1-650.282.4485.  It's just another rip-off originated by scum that have no problem hurting people.

DO NOT PAY THESE PEOPLE, better yet, report them to the FBI, & to Google.  My identity was stolen a few years ago, you'd think I'd be used to this kind of thing since I've had people literally threaten to mail bomb me, & my children...& have given my social security number, & personal details to prove they could.  Don't let them scare you, they'll move on to someone who will pay rather than waste time with someone who will fight them on it.  It's best not to respond at all :).
