Warranty issue for a broken iPhone charger cable

I bought IPHONE 13 on 12th of March 2024 and after 6 months the charger cable broke down I went to AASP concord plaza Cairo 11835 on 19th February2025 to check it and it really looks new, Mr. M Wagdy told me no there is a scratch on it(which is 2 mm) and refused to change it although I have Global warranty for one year
