this is the automated voicemail message left on my cell - verbatim
"Hello. We have been trying to reach you. this call is officially from IRS, Internal Revenue Service, The reason that this call is to inform you that the IRS is filing lawsuit against you. To get more information about this case file, please call immediately on our department number 202-793-8674. I repeat 202..."
I got a call from (722) 596-6514 and let it go to voice mail. The message said that "Internal Revenue Services" (it's "Internal Revenue Service," scammer idiots!) was filing a lawsuit and requested that I call (202) 239-2835. Yeah, 722 is a Mexico area code, SURE the U.S. IRS has a phone number from there.
I received the same phone call 1/15/2015 at 9am.
Extremely funny, like you said it's Internal Revenue Service not Internal Revenue Service(s).
To make this even more unbelievable, I currently work for the IRS, and have for the past 20 years. While working (for the IRS) I received this call.
No one ever said these scammers are incredibly intelligent. Plus I referred the number to TIGTA (internal police)
