Super annoying...they need to delete my number! It's pretty lame when they harass you with calls, over and over, at all hours, and all days, esp 8am saturday morning, but won't answer when you pick up. I could hear someone shuffling around in the phone, but they wouldn't say anything. smh so sick of calls like these.

Called on 12/12/2011 at 08:25am. Left no message.

A particularly nasty group of people who will call and call and call, never leave a message, and when one redials them back, refuse to identify themselves and get seriously mean.  
I'm turning them into my local phone company for harrassment!

Got one on 5/13 and 5/19 from a similar number, -3574. I didn't answer. They didn't leave a message.

I am; and they never leave a message.  When I call back, they refuse to tell me who they are.

Anyone else?
