Many thanks mende1
how can i complain against the service provider in my country, becouse they said to me to pay for the flash storage replacement although its under warranty.
Is there an email address i can use?
Welcome to Apple Support Communities
The warranty of the MacBook Air covers all the parts of your MacBook Air including the flash storage and the charger, so it's covered by the international warranty.
If you want to extend the warranty, you can purchase AppleCare
