It's Tony that deals with the orders, and I would imagine Tony and Harley who deal with the comments - and considering they've both not been around much recently, I'm assuming they're just not around - but Tony normally comments when he won't be around for delivery.
As for paying by paypal/credit card, I'd assume that was because you're in Vietnam - for some reason, those are the only payment methods if you're not from the UK, and possibly the US? I don't know.
Sorry, this isn't a great reply :P

Harley's Dad, and Harley is
