Incorrect descriptions

How can I make sure I oder the right variant if there are no pictures and the descriptions are incorrect? I want to add Spawn #316 cover C Barends to my order, but the Unknown description says cover A Mattina, cover B McFarlane, and cover C Capullo. The correct Diamond listings are cover A Mattina, cover B McFarlane & Capullo, and cover C Barends.
