Received a call today from this number claiming to be IRS and that there was a legal lawsuit against me.  Caller identified himself and Berry Allen gave me his id number and case number and told me he was going to give me info on the case and not to interrupt him.  When I asked him to slow down as I didn't understand his foreign accent he replied
you are a scam and then cursed at me at which time I hung up.  I am reporting this to the treasury inspector general for tax administration.
