Query: Ordered 10 screens, and ALL were defective

I ordered 10 of these adjustable screen inserts. ALL were defective.The screen was pulling away from the frame--right out of the box. The name of the seller says Promax, but the real vendor is apparently Crazy Dave's (Tool Supply)? If you call them, there is no answer and you haveto leave a message...lets see if they return the call. Doesn' anyone inspect the product before it ships? I can see missing one bad screen, but ALL 10? There is a serious problem here.
