I was getting the same calls with no one on the other side as everybody else. Today there were someone on the other side and she said it is from the NRS. Something about entered to win cash because I use one of the major credit cards....
missed call. tried calling back, would ring a couple times then hang up, or hang up immediately. I HATE SPAM CALLS! I feel like they waste my precious time on this earth.
Has been calling for days and I barely just miss it. I tried calling back and there would never be an answer, just a pick up and hang up. Finally picked up today and there was no answer. Extremely annoying and concerning.
