Marketplace sends wrong item

Hello, everybody about 30 min ago i tryed to buy an item from the points shop (Iron-Studded Mantle - 15 points) and instead of that the Marketplace gave me (Vicious Gladiator's chain Spoulders - 35 points) i don't even know why does this happened. I'm 102% sure that i made everything right. And yeah it's some stupid points...but still i've been collecting them for like 3 month. The item is still in my MailBox and even if i can't get my points back at least i would like to get the right item :/
