I just bought an iPhone 11 for my wife. She is upgrading from an iPhone 6! So I use Apple products and push them to the limit. I literally just pulled this phone out of the box so I don't like hearing these complaints about scratches. But I would offer 2 thoughts. First, my experiences with Apple tech support have been quite positive. You can call Apple directly and just tell them what product you are calling about. If they can't resolve over the phone they will make an Genius Bar appointment. Call: 1 (800) MYAPPLE
A second thought is this, for a phone that you are spending $800 or so for, I think a screen protector for $40 that has lifetime warranty might be worth it. So I invested in this Belkin screen protector and had it professionally installed at a local Apple Store.
Something you might consider:
Belkin InvisiGlass Ultra Screen Protection for iPhone 11

Hassle-free lifetime warranty
If your screen protector ever gets cracked or damaged, Belkin will happily replace it.
No, I don't work for Apple but I have used Apple products since 1989.
Yes, I hope this helps someone.
