i notice that the big Chloe lock is starting not to lock in,,,i had turned the ring over and over trying soo hard to snap it but it still wont work! do i have to open it up and fix it??? and also the 4 screw metal button behind the plate,,is starting to get loosen,,will it fall out what should i do is that all normal wear? why are the bags made that wayy or is it their craftsmanship defect???
