1. Complain to Tmall customer service, and attach a comparison of genuine and fake goods. However, the customer service terminated the rights protection on the grounds that there was no valid test certificate.

2. Most Tmall will be partial to sellers, so you can also take the following measures:

(1) Consumer complaint telephone number: the area code of the seller's location-123 15.

(2) You can also log on to the website of the Administration for Industry and Commerce where the seller is located and make online complaints.
