Total scams. I got one similar to that but it was some guy claiming he was a banker in South Africa, and that I was a relative to someone who owned an oil company who died. If you think it is legit, just ask them to submit information to you to confirm their identity before you can give them your information (ex. a supervisor, phone number, work information, etc.). I asked for this info from this "banker" but suprisingly () never got a response.
