Today i received same kind of call and the guy said that i won 2lack in a lukcy draw. I dontknow how that guy got my qtel sim card's number (written on back side), he got my name and Qatar ID number today. He also asked me to go to QIB tomorrow morning and call him, so that he will transfer the money to the cheque number. Please some one advice, what i need to do now, since i gave my qatari id to him.
