Sorry to hear about your recent experiences trying to communicate with Lange. Last year, I had an issue that needed to be taken care of with my Lange 1 moonphase and Lange in Germany responded same day to my inquiries by e-mail and was extremely helpful and also sent follow-up e-mails to ensure all was OK. I was really satisfied with their attitude and responsiveness (which contrasted with my experiences with PP). By the way, I reside in New York as an FYI. Hope you get better response soon.
