Who called from 4243774145

I have gotten this call for 3 days saying I will be taken into custody...

I have been receiving threating calls 2 and 3 times a day for this past week from a number 877-286-7421stating that the IRS has issued a warrant for my arrest for tax fraud, after hanging up on this so called man several times this past week I started receiving calls from this number. Same thing. This has to stop!!!!!

Two messages left.  Automated voicemail threatening to take into custody.  Fast busy signal when returned call.  Hoax.

They called me twice and left a voice mail saying the same thing as they said to everyone else on here getting this caller

They won't stop.  Invest in a call blocker and DO NOT pick up on call numbers you do not recognize.
