Sounds like these guys are busy! You would think that they would use a different name or different email address. I wonder if I should report this to the Better Business Bureau. Does that work if the company is based out of Singapore?
I had this happen a few times and almost fell for it. Got a real big order from some one in Somali. Claimed to be missionaries. Order several hundred pounds of coffee. Then asked me to buy them some cell phones. Said he could not buy them there. Said he would give me a 100 extra per phone. Sent payment by cashier check from a Miami bank. It all sounded to good to be true. Don't trust your bank they will deposit the funds into your account but when it fails to clear there gone. I called the bank the check was written on. Never heard of the people. Started getting calls demanding to know when there coffee was coming. They called for weeks. I never told them I checked with the bank. I final told them the check did not clear and they stopped calling. Never accept credit cards, checks or cashiers check until you have verified identity out side the USA. If for a big order ask for a wire transfer in to a empty bank account. I have been told if you give them you account # they can with draw funds.
