Who called from 9045121567

Called twice answered both, no one on the other end just hangs up

Keeps calling my phone all hours any day of the week. I answer and no one is there or someone (female) says hello then hangs up. Getting really old !

They call all day long and hang up when you answer

I don't know who these people are.  I don't answer any unknown or nameless callers. Keep getting calls from them anywhere between four, five, up to seven times a day, seven days a week!  which I consider harassment.

These people have called my house a total of 17 times in one day!! I don't answer  but looked the number up on caller ID and called back and got no answer.
