Hi Team Apple, My 12W power adapter has not working from yesterday. Plz help to replace and repair. Thanks Submitted for you fast reply.

You need to search online for your nearest, “local” Apple store location and call contact phone numbers and call to make an appointment to have your Apple power/charging adapter replaced under warranty

Failing that,

You need to contact Apple support via the contact support link located at the upper right hand corner of every Webpage of these Apple support communities.

Use the Hardware Repair & Battery usage & Charging support categories.

OR

by installing and using the Apple Support app found in the iOS App Store.
