This voicemail (“Trying to market you want to try to get contact with Carolyn and call back at 800-918-1839…”) was left on my phone from unknown phone number 228-215-0491.
The call back phone number 800-918-1839 is different from the voicemail caller’s phone number 228-215-0491. The call is “other-unsafe” communication “phishing” for information to commit scam/fraud.
