We're sorry to hear you've run into issues with your amika styling tool. Unfortunately, as any warranty coverage (including extended warranties) was an offering exclusively through amika HK, we are unable to facilitate any replacements under warranty.
While our distributor in HK (VIP Extra Club) no longer officially serves customers as an amika retailer, they will continue to provide warranty services for any styling tools still within the warranty period, and offer alternative options under its current branding.
We recommend that you contact them via their site - please provide them with as much information on your original purchase + your warranty request as you can.
If you registered your contact number at the time of your original purchase, you should be able to use this number to log into their site and easily request assistance (as your purchase record and warranty information will be on file)!
