Buyer beware

Be VERY VERY careful when your purchasing any sort of crafting items from any sort of vendor. If you happen to buy something that cannot be resold to the vendor, Blizz will NOT help you. They will not refund the item, they will straight up refuse to help. I asked for help, and ended up getting disrespected by a blizzard employee. when i tried to escalate the issue, they threatened to penalize my account if i continued to pursue the issue. Not only did they refuse to help, they disrespected me, and then threatened me. Please BUYER BEWARE!
