Mizudo offers three options for lodging a warranty claim: phone call, live chat on WhatsApp, or email. Your claim will be reviewed by the customer service team.
For a stress-free warranty claim, you need to provide proof of purchase, serial numbers, and photos of the installation and damaged parts.
All incoming shipments of products to Mizudo, regardless of type or reason, must be accompanied by a Return Goods Authorization ("RGA") number to facilitate any necessary repairs.
Please reach out to Mizudo to obtain an RGA number before shipping any items to ensure safe handling and processing.
There will be a non-negotiable 15% restocking fee for products returned without the original packaging or with missing parts or components.
Prior to returning a product for a refund, approval must be obtained from Mizudo's Customer Service team.
