You can't help it. You can try to report to the local consumers' association, for example, by telephone 123 15. It is best to submit proof that the goods and values of the other party are not in conformity, but this kind of complaint is rarely successful. It would be better if you could find more victims. There is also a bad way, that is, if you see someone who is going to be cheated in the place where they sell things, go over and tell him, so that the merchant may finally give you a refund.

It stands to reason that these goods should be sold within 7 days without loss and should be able to request unconditional return.
