I have only had my Chanel medium classic for a few weeks and only used it twice. My bag was quite full and I kind of forced the clasp down to make close. Anyway, the metal scraped together and it now has a deep little scratch on the twist lock. I can feel it with my finger so it's quite deep. I feel so sick because even though it's not noticeable, i know it's there.
Oh dear! So sorry to hear that; i know how you feel. I just bought a bag (not Chanel) and some stuff has been happening to it but no, it cannot be replaced or repaired; it sucks! I told my Dad and he said just use it as a rough bag; which is what I am doing with it now - i don't care how much stuff i carry in it and just throw it ard, on the table with files and folders all over (i.e. potential of being scratched even further) ; but it still hurts
You can try is Chanel can do somthing abt the clasp
