This number rang me just 2 minutes ago they just hung up when I rung them back I got a new voice message but the voice message was blank, after that I knew it was a scam I mean it had to be so I Googled the number and sure enough I was right. These people have rung me before and hung up I just thought how suspious.
Not sure who was calling but they left no voicemail. I googled the number and most people say it was GREENPEACE! This makes sense as I had recently signed a petition to stop Trawling.
