Agree with you. Frankly I would contact DJI and ask repair but making the point they not swap with refurbished one or similar and you will check this. In this case add some tatoos in shell and camera gimbal or so, take pictures of that as evidences and verify in trust at return. Or convene brand new one but you know can have other problems.
Good luck and all the best.
