Product failed in first test to stay on screen

I had high hopes for this product. It appeared to fit and seal well to the screen for the first 4 days. However, it literally fell right of after the phone dropped to ground from about 30 inches. The phone is encased with a Spigen cover that absorbs all impact and the phone fell on its back. The screen appears to have scratches on the underside and subsequently failed to make a new seal with the phone screen. It ultimately cracked in half when pressure was applied to the edges per the guidelines. Very disappointed. I've requested a refund but I'm hoping the company reads this as offers a replacement and possible cause but I'm afraid it's ultimately a design flaw related to the curved nature of the product,
