I got the same call this afternoon. Called the number. First time the person who answered was making obscene comments. I hung up. Called them again and got the IRS line about owing money and having four criminal charges. When I started to laugh the person said "f you ". I hung up.
Received a robo call from this number stating that I needed to call them due to four charges against me and have never even been to Miami. Reporting this number to the FTC.
"We would request you to get back to us so that we can discuss about this case before taking any legal action against you. The number to reach us is 305-396-8427" This was sent to me as a TEXT MESSAGE from [email protected]
