As already written below, we understand the point of the customer, but our position is still clear. If the customer needs additional services, which were not integral part of the order, he has to pay for it (approx. 2-3 days for checking all parts. Costs per hour 105,00 € for a technical clerk). Otherwise we provide all relevant legal information in form from our labeling and delivery note. Thus all parts can be uniquely identified. Furthermore we have to charge as also written below the separate stock place since 25.01.2016.
