Junk call.

Called twice in 10 minutes also did not leave a message the second time the first time I hung up

a male voice told me that my medical card was ready.  press 1.  I would also get a free medical alert button with the card, press 1.   I didn't say anything and the caller hung up within 15 seconds.

Answered the phone, but no one was there.

No one at the other end of this call?
