Who called from 5163843653

They said they were the IRS and were suing me unless I pay cash now.  I told them to sue me and they cursed me out and hung up.

Same message on VM just now

Just got two calls from these IRS scammers.   Filed a complaint with the IRS.  Probably won't get any action but maybe if enough people complain, maybe the Feds will go after these criminals.

same story here. reported to police. they assured me that this is a scam

Received a call on 22nd of March 2016. Didn't recognize number, so let it go to voicemail.
Message said I needed to call immediately and gave phone number. I called and it rang once and went dead. I have reported it to my phone carrier.
