This is the "Medical Alert" scam. Try to tell you they're ready to deliver it, paid for, blah blah. It's a scam, and they use many different phone numbers. When you block one, they call from another. We receive a call about every day from these scammers, never answer. Caller ID usually has a city and state listed: Oakland, CA; Elm Grove, WI; New York; Brooklyn; San Diego, CA and so on.
