Then when you are sure it is a fake, you must have proof of buying things in the store, such as an invoice ... If there is no invoice ... then I am sorry to solve it.
Finally, if you have an invoice, you can go to the store and ask them to apologize for compensation. If not, you can call the complaints hotline of Goldlion headquarters and the 3 15 hotline to reflect the situation. This must be done in person, which has a deterrent effect. Remember not to be impulsive and solve the problem in a legal and reasonable way.
No, you try. As for Goldlion's complaint hotline, Baidu will have it.
I hope my answer can help you.
