don't recognize number

IRS Telephone scam robo call.
Today's call came from 730-464-2227 claiming to b from the IRS who will file an IRS lawsuit against me and directing me to call 253-656-4712 immediately. Last call claiming to be "officer Charlie" from the IRS AT 571-526-0007. All numbers reported here, with IRS phishing website and Federal Trade Commission.

Called my home number claiming the IRS was filing a lawsuit but did not say who they were filing a suit against or leave an IRS representative contact name. When I tried to call this number to find out what was going on all I got was a busy signal.

There is a widespread IRS or "tax scam" being  practiced by scammers on both Canadian and USA residents.
USA tax payers should read this:

Short answer:
The IRS never initiates a contact via phone.
They always send a snailmail first.

Just ignore these thieves. I do not understand how come the authorities do not do anything to catch these thieves and punish them.
