# 我所訂閱的線上數位課程可以退費嗎？

【若您購買的是課程影片未上架的「預購課程」】：影片上架前，若因學員個人因素取消需取消訂閱，請洽詢 OMIA 客服中心為您查核及辦理相關程序。

 

【若您購買的是已開課的「一般課程」】：依行政院公告之「通訊交易解除權合理例外情事適用準則」規定，OMIA線上數位課程不適用於七日鑑賞期，因此並不受理退款，也無法要求更換成其他課程。建議您購買線上數位課程前，先詳細了解並確認內容，或先觀看預覽影片或免費課程單元後，再進行訂閱購買。

 

團購方案亦適用以上政策。若您團購後，有尚未開通的課程序號欲申請退款，請洽詢 OMIA 客服中心為您辦理相關程序。OMIA 將扣除團購所享的優惠價差後，針對未開通的課程序號進行餘額退款。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.omia.com.tw/support/tui-fei-yuan-ze/wo-suo-ding-yue-de-xian-shang-shu-wei-ke-cheng-ke-yi-tui-fei-ma.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
