this number has called me numerous times for days now. I dont answer phone calls if i dont know the number. there have been no voicemails left and its really starting to bug me.

This number keeps calling.  I have no idea why.  There is no message.

This number has called several times a day for three days, and I do not know who it is.  I tried answering two of the calls but there was a funny tone or no one there.  I don't know who it is or why they keep calling!

Continuously calls. Won't leave message or speak.
Very annoying.
