iphone 11 paint chipping

yup you should have heard about the iPhone 7 paint chipping and I can DEFINITELY say it’s a very big issue. It happen on my fiends iPhone 7 and now my NEW iphone 11 . I feel very disappointed I handled it with utmost care. paint chipping started with the anodised aluminium near the camera lens then it increased and increased and even spread to other parts of my iPhone such as the charging port and also the SIM card tray and many spots on the side. It’s very disappointing as I had a case on it all the time and it has only been 4 months since I bought it . I have even went to a authorised repair centre and they said it’s cosmetic issue but it’s still a issue which I am very sure not caused by me and it was problem caused by Apple so I am very disappointed a expensive phone from a well know company sells phones with this issue and says is cosmetic and caused by wear and tear by the user but it I am 100 percent sure it was not caused by me. The white spots keep on increasing, but for apple it’s only a cosmetic issue. But for me its a big issue I keep my phone very safe as I worked very hard for it as I used all my savings on it

is there any way I can fix this issue and if you also have this issue plz share this thanks:)
