3ヶ月前にDell Japan（Amazon Japan）でAW610M、AW510Kを購入しました。黒塗装が自然に剥がれて保証期間内の修理をお願いしたいと思います。手順を教えてください

 

I bought AW510K (Lunar white) and AW610M in March 2022 (Optional color is white). I seldom used them but the black paint is peeling off spontaneously. Within warranty period, I want to request help. As far as i know, the keyboard and mouse don't habe service code. So I can't proceed warranty service in website. How can I proceed warranty service?
