I keep getting calls from this number saying that I committed a felony, when I call back the number is giving me a message saying that is disconnected and no longer in service. Try ti fine if the number is a government agency and noting come up in any government offices.
It's a bogus government agency, trying to cheat people out of money by intimidation. These crooks know they're fake so they use dummy numbers to avoid being traced. With no kind of answer from the numbers they call, con artists can only waste more time trying, or quit calling. Any kind of answer is required for them to have even a bit of a chance.
