Thank you Gerd Wienzek
Dear Gerd Wienzek,
Thanks for your concern,
Based on your payment policy we can get the payment by payment gate only
Private letter: It keeps your information only.
Regular letter: Your information will be listed with another applicant; details.
Some customers do not want other people to see their information, so they apply for private letter. so it;s optional service.
