left no message

this numbers calls all the time but i dont answered it they never leave a message  

I don't know who this person is and they keep calling,leave no message,i answer and they don't say anything,i have told them to stop calling,soon ill call the police if they keep calling

I just received a call from this phone number and when i answered it, they did not say anything. I could hear noise in the background. After i said "hello" the second time, they disconnected.

This number just called me and didn't leave a message. I don't answer phone numbers I dont know and plus if it's really for me they would leave a message.
