Who called from 3364858071

Repeated calls for several weeks. Never leaves a voice message, no one speaks when we answer.

New wrinkle. Call went to answering machine, at the tone a phone began to ring, it rang 5 times and no one answered.  This repeated calling makes no sense and is annoying to come home and find one call after another and now this.

I called it back and it had an automated voice that said hi, you have reached the sweepstakes entry center.

The same thing has been happening to me 2 or 3 times a day for 2 weeks.   I do not answer cells that I don't recognize.  But. check my voice midlife in case I need to return the call.  This Greensboro phone number does sometimes leave a message. but nothing there or a phone start ringing,
Very annoying!

They keep calling my cell don't leave message I have the do not call on my house And cell wish they would stop it's very irritating
