People please please please be million miles away even about thinking to reply or respond to such emails or sms. These are completely frauds, they will lure you by such big big winings amounts and get advance money from your or even take sensitive and confidential information of yours..like bank acc num, pasport num, pan num, mobile num ..etc.
This wont take you anywhere than only quick sand.
I strongly believe these are the nigerian frauds kind. Please report this to ciber crime dept.
Also understand one thing...
''Nothing in this world come for free, everything has a price tag, our own earned money come with lot of hard work...we ourselves think twice before doing charity, forget about being charitized :)''
