I keep getting phone calls from this number. When I answer, all I hear is silence.

repeated phone calls from this number and nothing on the other end of the line. Kinda annoying.

has been calling non-stop. googled the number and found this. so the next time they called i picked up and didnt say anything, there was a woman on the other end who said hello, i hung up.

Why haven't you try to find out who it was?
