I got this phone number on my phone telling me it was a irs

Phone call with middle eastern accent gentleman claiming to be IRS getting ready to file claim against me. I asked if he was in Washington DC and he said yes. I said if he could put one person on the phone with an American accent, I would continue the call.  He laughed and asked why I didn't believe him.  I then continued to berate him and asked if he would like to have someone trying to steal money from his parents this way and he replied "no". I called him unethical and immoral and blocked the number.  This kind of BS call is getting old.
