### **Customer Inquiries**
Customers may send messages to the developers including maintenance request, error report, sometimes request for refund. You can read them in your email and reply to the customer and the reply will be sent to the customer by email notification.
### Request for refund
* ONE store users can request a refund through Contact Seller on the app detail page.
* These inquiries are sent directly to the developer’s email address.
* If a refund request is received through **Contact Us** in the **ONE store App** or through the developer’s customer support channel, please submit the request through **\[Developer Center > Help > Contact Us]**. \
We will review the request and assist with the refund process.
* If the developer does not respond to a customer inquiry for more than **3 days**, the ONE store Developer Center operations team may process the purchase cancellation to ensure a timely response.
* In particular, for paid apps, post-purchase support plays an important role in the app lifecycle. \
Please respond to inquiries from ONE store users as promptly as possible.
* If verification of the **customer’s TID, TXID, or payment receipt number** is required during the purchase cancellation process, you must also confirm whether the customer has consented to provide personal information.
