Critical design flaw

the reason why I chose this harness instead of other more popular brands like Puppia was because the neck and the body of the harness were supposed to be fully adjustable. however, there is a big problem that limits the adjustability. If you want to make the neck space smaller, you can only adjust it an inch or two because the thick metal component cannot pass through the small fabric loop. This is difficult to explain but can be seen in the photos attached. I wish I knew this item could be returned, unfortunately now my return window has passed.
