My RT-AX82U router is now a fancy paper weight

The adapter broke for my RT-AX82U, and it is less than a year a old. So I contacted Asus for a replacement and their response is, they do not offer this part separately, and there is nothing they can do, so now I am sitting with a high end paper weight. Below is their direct response incase I have miss read it:

Dear ,

The adapter is not produced separately, so unfortunately so is no way to be ordered from factories. That's why we cannot help you, it's not because we don't want but just because no spare parts are available.

Thank you for your understanding.
