i received a call saying they were from the BBB and i had won a prize like money and a Mercedes benz. ACTUALLY first he called and says "can u call this number back" so i did.  after i called him back he said i won prizes.  funny thing is i NEVER use BBB except for the first time just a few days ago.  he kept saying something about delivering prizes to my house so i asked for the address on file and he didnt know what to say, so i hung up.  also he clearly was not an English as a first language person
