This often happens in society now, but it is very difficult to protect rights.

Reason: there is no fraud in the transaction process, which means it is not a fake.

There are also these things, which are natural jade, whose market price is not certain, and there is a phenomenon of willing to fight and willing to suffer.

Then the seemingly reasonable department you mentioned actually has no absolutely convincing rules, so in the process of safeguarding rights, consumers will voluntarily give up because the cost is too high and the manpower and material resources are too high. Even if they persist, most of them will not win the case in the end, for the reasons I said earlier.

I suggest you negotiate with the owner.
