Query: cut out does not stay in place

I ordered this product about a month ago for my brother who weighs about 200 lbs. When he was trying to transfer, the cut out would pop up out of place and cause him to nearly fall. Then we epoxied the cut out in place, then the notch which is suposed to keep it from falling through broke off and once again it was not secure.
