Sorry for the loss of money, on the next scam in a moth or two after they know, you are not going to send money and/or when they know you have found out. someone will email you that sounds like they are from the US emmbassy or from the Ghana government, and that they have gotten some of your money back or there is a fund to help you get your money back but guess what you have to send >>> dollars to get that money.
next do be cautious they are good at what they do, they have prepared scripts that have a answer to any question you ask.
