This situation is not encountered by one person. Lottery discount is a form of promotion. How can something as expensive as jewelry be bought for tens or hundreds of dollars? Even if you buy a color, it is still money. So first of all, I hope everyone can avoid this situation and stop being cheated.

Ways of safeguarding rights:

1. You can communicate and negotiate with the seller and put forward a reasonable claim for return and repair.

2. Complain to the relevant departments of consumer rights protection, and let the relevant departments mediate between consumers and sellers.

3. Seek the help of media supervision, expose the seller's behavior to the media, let more consumers know the seller's irresponsible behavior through media exposure, and put pressure on the seller with consumers' doubts. In the face of public pressure, the seller will choose to deal with it seriously and take responsibility more often.

4. resort to the law to protect rights according to law. The way for consumers to protect their rights is to file a lawsuit and protect their rights and interests through the law.

I hope I can help you and adopt it.
