Business ProfileforAmerican Cash Awards

This scam got 1500 dollars from us. They said we won a huge amount of money and a vehical of choice. All we needed to do is have the money on cards from Walmart and hve them ready when they come with our prize money and vehical. So we got the cards. They called to see if we had the cards. Then they ask for the numbers on the backs of the cards. I told th3em no,and that they could get the money. He said it was so they could make sure we had purchased the cards. I gave him the numbers, agaist my better judgement.So I realized I could call and tjey had taken the money out thaat vety day. They were uunable to reverse tthe transaction. They called and said Az. had a tax to be payed before we could recieve the money to the toon of $50 000. WE Kept getting call several times a day for a month or two. This all happened last years.Now it's starting all over again. Same voìce, different àmount of prize money, but same lines. He's calling again and again and again.!!!. So,... BBB. how can we stop these calls and get this guy behind bars? Can you help? Can you tells who can help us? We changed our phone numbers. Now he's calling both of our numbers.Help! We are 70 years old and just want some peace. There has got to ?e somethìng that can be done!!
