904-506-4038 - 'Unknown name' was caller id & typically calls with no real caller id that doesn't leave a message are usually spoofed & will be telemarketing/solicitors that have questionable honesty.
Fake and illegal IRS call. totally bogus. Illegal. The IRS never calls you. This is a scam. report this activity immediately to the IRS and the FBI
I get 2 or 3 calls from this number a week and it's just dead air.
