To help us assist you as quickly as possible, please provide complete and accurate order information when contacting us.

If your order was placed on HIEHA.com, our website support team will review your request directly.

If your order was placed on Amazon, TikTok Shop, Walmart, or another marketplace, HIEHA.com may not be the seller of record. In such cases, we will first verify your order information and, where applicable, route your request to the appropriate support team.

Important Notes

• Returns, refunds, and exchanges must be handled through the original purchase channel and are subject to the applicable policy of that platform or seller.
  
• If the platform return window has expired, we may still assist with troubleshooting, warranty review, or product support, where applicable.
  
• Submission of a support request does not guarantee a refund, replacement, exchange, or warranty approval.
  
• All support outcomes are subject to order verification, product review, and the applicable seller / platform / warranty policy.
  
• Please do not return any item without receiving return instructions or written authorization from our support team.
  
• Incomplete order information may delay our ability to verify your purchase and process your request.
