Get calls from this number all the time, no one answers.

keeps calling my cell phone,  when I answer no one says any thing and after a long pause they hang up.

This number has been calling me several times a day, never pick up, but very annoying.

Someone at this number keeps calling me every day...I don't answer it, but they don't stop calling

I am getting several calls from this number too.  I know it's a scammer, but I say helloooooooo... hellooooo  and last time when there was no response, i said "if you aren't going to talk then quit f****ing calling my number!" and hung up.  Then you can hear a very quiet "click".  It must be robo calls and a person probably answers the first one who picks up, then the rest go unanswered until next time they call the list of however many they call at one time with the robo-caller.
