Screen Replacement Program Denied

I normally have great experiences with Apple products. However my experience with Apple Watch was quite poor. I bought mine in 2018 and after using for a couple of months it just stopped working. The screen went blank. I brought it to the assistance and after a while Apple replaced it admitting that it wasn't supposed to happen. I started using the replaced watch and a few months later I got a crack form along the rounded edge of the screen. I brought it to an Apple Store in Aventura,FL. The attendant said he had to send it to the factory and that I have to pay USD160 because there were signals of scratch on it. Well, I am an extremely light user, who never dropped the watch on the floor and I explained that one day the screen just cracked. After delivering the watch I realized there is a Screen Replacement Program with the exact description of what happened with my watch, so I really don't understand why they didn't just replace it. Summarizing, it was quite a bad experience. Hope Apple will do something about it.
