Received a few calls on my office number. They keep calling but don't talk when I pick up the phone.

They keep calling my cell phone,  from this number: 858-956-0045, day and night but when I pick up the phone, nobody is on the other end.

Same thing here. They have called twice now, during the day and no one is on the other end.
Strange.

Whoever calls twice a day.  Once in the morning and then in the afternoon.  When I answer there isn't anybody at the other end...

It's something called "American Banker" but not the newspaper of a similar name.  Trying to give something free away and they call here all the time.  It's quite annoying.  They don't stop.  I think they're calling direct lines of assistants of people in the finance industry, so if that's you, and you see the number on your incoming screen, introduce yourself as your boss and tell them to stop calling because that's the only way I got them to stop.
