You need to bring the broken product and the standard warranty card to the service center. When transferring equipment for repair, from the service center you receive either a work order or a receipt, which indicates the most detailed information about the product, the nature of the breakdown you claimed and (or) manifestations of the defect, as well as detailed information about the customer. As a rule, these documents are numbered - when contacting the service center, it will be enough for you to name the receipt number and you will receive information about the cause of the breakdown and the timing of its elimination.
