I received a message that said I there was a lawsuit against me. The message contained no case number to reference and provided no company identification. I tried calling the number back twice, but the call disconnected each time. I was unable to speak to anyone. I researched the number and came across this site identifying similiar messages.
I received call from 3602626451 with a recorded message saying: "This is my last opportunity to pay an IRS debt and to call phone number 3602626451 immediately." I called twice, it was busy, third try got message to leave message to get call back, called again and nothing at other end of line, went dead.
