Called and then hung up.

They call several times a day.   They finally had someone on the other end of the phone, but when I asked who it was they hung up.

They call our office about once a day and hang up. Not sure whether it's a business or a person but it's pretty annoying. If you call it all you hear is a busy tone. What a waste of time for everyone involved!

Called and when I pick up, now answer
