It's a scam. Just got a call reference the same case. These people have no life but trying to get other people's money. the Nigerian scam hit me big time on Christmas 2014. they sent me a check for 4700 and I ed to my account. Then they want me to withdrew 4000 and moneygram for fees and tax. two days later gotta a call from my bank that the check was invalid and I already withdrew the money out. My bank didn't found out until two days later it was my fault and I hope no one gets caught up with these no life people. God will punish that for what theyve done.
