Got a pre-recorded message from this number saying IRS has been trying to contact me and will file a lawsuit

These are IRS scammers -- sound like Indians -- I called them back several times and had some fun with them. The "Senior Officer" I got connected to at one point started cursing me out in pidgin English. I'm no fan of the IRS, but I'm pretty sure their senior officers don't swear at customers in heavily-accented, kindergarten-level English. I wish the IRS would pay as much attention to shutting down these scammers as they do to collecting our hard-earned money.

Received pre-recorded call at 6:20AM Pacific Time from New York
Claiming to be IRS and needed a return call immediately.
Blocked any further calls from this number!

They called and said they are investigating my case and wanted my address

Received a message so we called back!  Total scam!   Talked to Jordan Russell with badge number gs4016.  Apparently, they got super angry when we told them to send a letter.  It was comical.  Now on blocked list.
