Customers might contact you to request a refund on your Asset. However, because they made purchase through the Asset Store, the store manages refund - not individual publishers.
If possible, try to help your customer resolve their issue to avoid a refund. If a refund is required, then you must request it from the Asset Store on the customer’s behalf, using the following process:
1.要求用户向您提供购买资源时收到的发票。
2.登录 Publisher Administration 页面。
3.使用 Verify Invoice 选项卡验证发票。
4.验证后，使用与发布者帐户关联的电子邮件地址向 assetstore@unity3d.com 发送电子邮件。您必须以附件形式提供发票或直接提供发票号码。
下面是申请模板：

Please refund the following asset(s)
Publisher Name:
- Asset name(s)
