If you want to deactivate your shop (or one of your shops), you have several options:
1. Log in to your account and click on 'Public Shops'.
2. Select the shop you want to delete and click on the three dots in the top right corner.
3. You can then either 'unpublish' your shop, which takes it offline and allows you to make changes.
4. If you are sure that you want to delete your shop permanently, click on 'Delete Shop', and it will be removed immediately.
