Be careful don't victim of fraud

Unfortunately these days we are seeing fraud in all over the world because of poverty or because of mental problems or just to show other that we are a keen person !
each person has a main reason for fraud even it's not acceptable for us.
I want tell you a real story about fraud that had occured for my brother about four months ago.
Around four months ago when my brother checked his credit account (Online) he understood someone is useing  his credit card  in Vancouver .It was used several times in Gay Bars and future shops and Ikea....
After that my brother called to the bank and explained the story for them .They canceled his credit card to prevent  more uses.The  bank asked  my brother some documents that prove he was in Calgary exactly at that time and after that they returned all the money to his account but they  could'nt fint  that man.
Fortunately my brother would'nt be tricked but  I'm sure there are lots of people in the world that they are the victims of such as this fraud.
