Caller Name ID = "San Antonio TX".  Voicemail only caught the tail of this recording: "... Internal Revenue Service.  This reason of this call is to inform you that IRS is filing lawsuit against you.  To get more information about this case file, please call immediately on our department number, 210-229-8504.  I repeat, call..."  Clearly a scam.  I have no IRS issues, and in any event, IRS does not make initial contact by telephone.

They just called again.  Identical Caller Name ID, identical recording, from identical phone number.  The calls were about an hour and a half apart.

Have gotten three over the last two hours. Question. Do you have Comcast? We have noticed a pattern that after we have a friend phone call, scams immediately follow. Does Comcast give live phone info to scammers?

I knew it was a scam, but I felt like having some fun, so I called the number and acted like I was real concerned.  I swear these guys need a better phone system, on top of learning how to speak better English.  The first guy I was talking to asked if I had received the certified mail (documentation) that was sent to me in November  I told him I never received anything from the IRS.  Then he went on to tell me I needed to make the payment and I could go to WalMart, but he had to transfer me to another person (his supervisor) that would tell me what I had to do once I got there.  I also asked why can't I just go to my local IRS office in Seattle to take care of this in person.  He put me on hold while he "checked" with that office to see if they could.  Came back on the line about a minute later and told me they could not.  I finally had enough fun for the day and told the guy I knew he was a scammer.  He hung up on me.

I also received a call from "supposedly" the IRS saying the IRS is filing a lawsuit against me, and to call immediately.  I did not return the call, because I know the IRS doesn't contact you by phone and I have filed taxes every year including for this past year.  I immediately googled the phone number and found several references to scams from this number.
