Let it go to voicemail - was a computerized voice telling me about a case number, "The moment you receive this message I need you to retain the journey of records. The issue at hand is extremely time sensitive. My phone number is 678-264-8070. Do not disregard this message and return the call now. If you don't return the call then the only thing I can do is wish you a good luck as this situation totally unfolds on you. Good bye."
I'm not sure it could have sounded more scammy if they said "This is a scam call trying to scam you with a scam."
