If you buy fakes, you can directly complain to Tik Tok merchants about selling fakes. You need to submit a false certificate after the complaint. If the verdict is established, the merchant will be punished and the complainant will get false compensation. If the transaction is in progress, please apply for a refund and contact the seller for negotiation. If both parties cannot reach an agreement on postage, refund, etc. , you can apply for customer service intervention after the seller refuses the refund agreement, and upload valid vouchers for Tik Tok customer service to verify.
