I was not aware of them requiring KYC in order to order, but then how was I able to place the order? I've already payed in bitcoin, will they refund me?
I ordered a couple S15's to ship to US
You had to check it, don't you know that almost every service requests KYC? Even shapeshift too. Bitmain has KYC for some months, as I remember from summer. Maybe try and email them to refund or wait if they ship without KYC documents but I have huge doubt that will happen, in both way they'll require KYC, your money will be in stuck for some time, before they verify you.
