Not observant staff caused large frustration. My wedding ring was checked under the wrong warranty several times without my being notified by the staff. When one of my diamonds fell out I was told that I didn't have my ring checked so it wasn't under warranty. I showed the documentation I had which does not show a product name. Unfortunately the paperwork was for my earrings not my ring. Since they couldn't confirm with the staff (three different people in the last 2 years) checked my ring instead of the earrings that I had paperwork for, I would be responsible for the repairs.
