Who called from 2405821450

Called me saying they were the IRS and said I was going to be arrested

Received call from this number claiming to be IRS
Hung up as IRS will not call you ( they send mail only for initial communication)

If you receive a phone call from these people goto

And fill out the form to get them arrested for impersonating a government official

I just called the number back and told the lady she was going to be arrest for pretending to be the IRS.

She laughed and hung up.
