You can call the merchant complaint hotline 123 12 to make a complaint, and the merchant law enforcement officers will assist consumers in protecting their rights. It should be noted that when consumers buy alcoholic products, they need to write the product number on the invoice, and the invoice needs to be stamped with the true and effective official seal of the merchant, and then apply to the Anti-counterfeiting Identification Center of the Municipal Liquor Monopoly Administration for alcohol identification.
