[New car] Car papers disappeared by post

Hello together, sorry I may not have found the appropriate subforum. I ordered a Skoda Octavia RS. This is now available since 31.01.2017 at the dealer on this day we have also made the appointment for collection on 07.02.2017 and the dealer has put the papers “on the way”. The papers have not arrived to this day. The whole was sent as a normal letter Now the question is how to proceed. The statement from the dealer is that it is determined The Postweg is therefore Nuremberg-Munich maximum duration of two working days. How would you proceed?
