Who called from 4154624132

Wife answered call. No one there. Called back on my cell. Not a working number.

Called again today. After a delay, "John" came on the line to advise about a medalert offer. Now to block.

Complete scam, don't answer 'yes' to any calls that ask you a question requiring a yes or no answer. The recorded yes can be used to sign you up for all kinds of offers. If someone asks you "can you hear me?" from a number you don't know, just hang up.

Called but didn't leave a message.  Probably a scam or robocall

John from medalert is going to try to record your voice saying yes so they can start scamming you.  Becareful.
