Should a customer receive defective goods, the customer can return them to you as a warranty case. For this purpose, the customer registers the warranty case in his account. You as a merchant must replace the goods immediately or refund the purchase price, whereby a solution can also be requested bilaterally with the customer. You aren’t actively informed about newly created warranty cases (e.g. infomail). But you are advised to regularly check your CMI account for new warranty cases.
