Seems easy ONLY---
Post the real PM's Post the death threats....
If not... you probably are gonna lose some business over 0.2 btc which is why when customers pay for products, the business always tries to treat the customer right and do right by him. I agree guy was an asshole, but after all that, any of us would have been... He said no re-ship, refund.. and you argued, then again, then when he finally says ship em he gets more attitude. You can't just not give him product or payment. That's not a business.
PM sent, hope it's much more clear for you now.
I take it back. If that message did come from the customer, he should get nothing. It's not only a death threat but racist. I would still buy again ONLY.
