Scammer is back in action since 2011 I see. But as soon as I post a current active complaint, these 2011 complaints will go away. Most didn't know what caller wanted. One said it was a woman that called them & this woman tried to convenes them they had a Shell gasl credit card, which the person said they didn't. This is a spoofed number, which means fake, this is why when people try calling it back it's invalid. Only scammers do this. A current complaint on another web site, most say caller hangs up but one complaint said it was about vehicle warranty........another scam.
