If the seller of the goods purchased does not reverse the difference, the consumer may take the following measures:
I. Understanding the seller's policy of refunding the price difference

Before buying a commodity, consumers should be aware of the seller's exit policy. Consumers have the right to demand that sellers honour their commitments if they have made a clear commitment to re-offensive prices when selling commodities。
If the seller does not make an explicit commitment to refund the price, the consumer may consult the relevant laws and regulations or platform provisions to determine whether he or she has the right to request a refund。
Ii. Settlements in consultation with stories

Consumers can attempt to communicate with sellers, explain their situation and make requests for refunds. In communication, consumers should remain calm and rational in expressing their claims。
If the seller agrees to refund the price, the parties may agree on the specific manner and timing of the refund. Consumers should ensure that the results of the consultations are consistent with their interests and that relevant evidence is preserved。
If the seller refuses to refund the price difference, the consumer can file a complaint with the relevant regulator or consumer association. In the event of a complaint, the consumer should provide evidence such as detailed purchase records, the seller's commitment, so that the regulator or the consumer association can better understand the situation and help。

In accordance with the relevant provisions of the law of the people's republic of china on the protection of consumer rights and interests, it may be unlawful for a seller to refuse to comply with a promise of refund. Upon receiving a complaint, the supervisory authority investigates and deals with it in accordance with the law and protects the legitimate rights and interests of consumers。
In conclusion, in cases where sellers do not refund the price difference, consumers should first understand the vendor's exit policy and then settle it in consultation with the seller. If the consultation fails, the consumer may file a complaint with the relevant regulatory authority or with a consumer association to defend his rights。
