f the period of possible return has not expired, the consumer is entitled to a full refund of the purchase amount. In the case of the sale of counterfeit products, the seller has no right to insist on the return of the goods, because it can be sold to another buyer. You need to appeal to an independent examination to confirm adulteration of the product. I also advise to provide the seller with the documents of purchase of goods, citing possible legal repercussions. Insist on a full refund, providing a certain framework for taking the payment. If the seller refuses a refund, you must file a claim with the court where the buyer is entitled to claim damages and compensation for moral damages, and to impose a fine on the seller in 50% of the amount of the claim. Attach to the statement of claim a copy of the complaint submitted by You to the seller.
