Hello What if you order a spare part, this is delivered, you agree on an appointment in the same course in the werksatt, and the article is delivered incorrectly. After that, you have been advertised with the correct number of parts that will be delivered please replacement. Replacement came quickly and it was again the wrong item. The workshop says now : if the appointment is cancelled 1 day before, a replacement for the downtime is required. Can I charge the dealer, o who only try at several?
