Nasty IRS scam. When I called backed the first time, some guy with a thick accent tried to tell me I owed thousand in taxes. When asked for IRS id he hung up. He did say that the "authorities" would be at my door in 45 minutes for an arrest. Second time I called back to be annoying there were obscenities and threats to my wife. Claimed to be Pakistani.
This number called me left voicemail with beginning cut off said "is filing a lawsuit against you please call our firm immediately at 206-259-6157. Then when you call this number it's says the number is either changed or no longer in service.
