You were caught cheating, this isn't Dgameskys problem ... it's yours. They lost their gold and they wouldn't want to do business with you since you obviously are doing things that are attracting attention.
I've bought some 15, 000gold from them over a couple of months. They've always been great, I would recommend the auction house its the easiest and fastest way to get services. They are not the cheapest, but if you go down that route be prepared to be scammed. I went online to find a power leveling group and go figure the Google sponsored links were all scams. So I'm back to Dgamesky.com, they're great!
If I remember correctly, they do require a valid phone number for your first purchase. They will call you to confirm you are a real person. Just another reason I trust them over other "cheaper". Best of luck in feeding a chinese family :).
