Take it to an Apple Authorized Repair shop, perhaps. My wife dropped her Air and bent a corner the AA store we bought it from agreed to bend the corner back. It looks ugly, it cost some money. But they have the skills to take it apart. And I'm hoping they didn't put the repair into the Apple repair computer system. We have an AppleCare repair coming up, and plan to take it back to them and argue that the problem is unrelated. I think a corporate Apple store would void the warranty if they saw the damage.
Good Luck, and condolences. 🙁
