Only phone calls, the don't do email.
Note the holds can be as long as 30 mins. So much for long distance call
Shipping by AE is insane maybe usd$70-140 from a other thread.
It's best to buy on amazon or eBay.
Even in states not sure how many ppl fly to ORD and drive 1 hr to buy shoes.
Actually, they do email orders too but the question is how comfortable are you with sending your credit card number in clear text over emails. As for calling to US, Skype is your friend.
Best way is get AE to ship to comgateway since domestic shipping is included in the second's price. The only issue is returning the shoes once you get them is gonna be a pain, so you probably will need to accept whatever you get once CGW ships them to SG.
