Looks quite spammy, also this is not proper section for posting currency exchange related thread.
It is not easy to deal with western union for bitcoin exchange, you might end up losing all your money. Don't deal with this guy without any escrow in middle.
You have your creditcard access you can charge back.
Once I got money and you got you btc too.
Don't be silly
You scammer! YOU don't be silly!
Charging back credit card payments to Western Union is not easy as their terms and conditions state "no refunds".
You are a scammer.
Everyone, use escrow when dealing with this person!
