Who called from 4059729077

the number was (405) 972-9077 it rang once and ended..weird..may be telemarketer

received a call from this number saying the IRS was filing a law suit against me. Never called back. The IRS would never call you to tell you about law suit

Called, no response for 15 sec or so,  and I hung up

Rang my cell phone 3 times, then hung up. Looks like the same MO from everyone else.

One ring then hang up is usually puter generated call.
The puter calls, if you pick up, it hangs up.  Then they know you will answer and about what time you will answer so they can have a telemarketer call you back.
