He request for extra money to be deposited into his account VIA western union money transfer, then I waited three week for the money to be deposited into my account but nothing was there.
Is there any insurance thing?

Anyone who asks for a Western Union transfer and isn't friend or family is a scammer. Please post the emails he sent. They are probably script, and other possible victims will be alerted when they search for text in the script.
