How can I protect my rights online when problems arise with whole-house customization?

When problems arise, don't rush to post online. First organize the contract, drawings, payment records, on-site photos, and chat records, and list your demands clearly in chronological order. Start with the merchant's after-sales service and the store manager, and keep written communication on record. If no agreement is reached, then complain to 12315 or the local market supervision authority, attaching evidence numbers. Exposing the issue on social platforms can be used as a pressure tactic, but be careful not to disclose personal information or exaggerate the facts. If environmental issues are involved, you may request handling according to the contract. On our side, it is explicitly returnable if not environmentally compliant, with a ten-year warranty on cabinet bodies, excluding water damage and human-caused damage.
