In the first call i recieve it because its an international(pakistan) nos. [protected], after the person who is talking with me saying that you win the sum of rs. 25 lakh in our lucky draw which is choosen by selecting the lottery phone nos., and he is also ask about me that, what you do? Whats ur account nos.? How many balance do you have now in your mobile phone?... I thnk that its' any kind of fraud because i am an Indian and the incoming is from Pakistan and he is also not talking with me in an official language of a company(which means talking in hindi or may be urdu) and also telling me that tomorrow on 9 a.m one of our company's member [surname only i remember(Kumar)] will conversation with you about how to deliver your cheque and all... And after few minutes the same nos. recall me back 2 or 3 times, but i didn't recieved the call...
