I am with the IRS IDno75708 miscalculations from 2011 and 2013, (?) sent letters in November and February, (didn't receive) we are sueing you (couldn't hear amount) call mostly unintelligible , said I would call back on cell phone, did no, connection very bad, wanted my phone number and address, felt wrong, looked up summer, here I am.
Just received a call and a threat from someone who could barely speak English but claimed to be from the IRS. He said he was going to send the police and became hostile. I told him to go ahead and send them, then I hung up.
