I suspect that what caused the failure is a lack of soft close. When closing a drawer, if the slide is smooth and doesn’t have a stop, then the drawer front gets a huge impulse when it collides with the cabinet body. Since the entire kitchen likely has the same craptastic quality, the first step is to instruct everyone to close the drawers as gently as possible. Then consider retrofitting soft close mechanisms to the drawers. And maybe even start saving up to replace the cabinets because more failures are likely.
