The seller must provide you with an order confirmation for both goods and service sales. It must be delivered to you within a reasonable time and at the latest at the time of delivery of the goods. In the case of services, confirmation must be provided before the service is performed.
The confirmation must include, for example, information on the right of withdrawal and the duration of the agreement. The confirmation must be sent in a permanent manner that prevents any possibility of altering the information later, for example by e-mail or on paper.
