The buyer has the right to a justified complaint or reclamation and the return of goods in the following cases:
If the product has a hidden defect (the defect that could not be detected by the usual inspection when taking over the goods) which the Buyer determines after opening the product - the Buyer has the right to unilaterally terminate the contract and refund, replace the product, eliminate the defect or reduce the price.
The seller will consider the complaint valid if the product inspection determines that it meets the conditions for a complaint in accordance with the Civil Obligations Act and the Consumer Protection Act. In that case, within 15 days of receiving a valid complaint, they will replace the product or refund the full amount paid upon termination of the Agreement. If, on the other hand, it finds that the complaint is not valid, ie if it rejects the complaint, it will notify the Buyer within 15 days from the day of receipt of the complaint.
The Seller will accept the return of damaged, defective or incorrectly delivered goods at its own expense, if it is determined that the complaint is justified and that the Buyer did not affect the correctness, damage or any defect of the goods.
In the event of a justified complaint, the cost of replacement with a new product is borne entirely by the Seller.
