This caller, "John", claimed to be scheduling the delivery of a paid-for medical alert system system. The phone records show that the call came from from Denton, NC. I have received the same message from other locations in the past. It tries to sound like a live person, but it can't respond to unexpected responses, although it has improved since the last such call I received. I believe this is a known scam.
This is not the first call I have had from these medical alert system scams. They use other numbers that I have blocked. They target older persons. I will block this one too.
