Important information on fraud prevention

We would like to point out that at no time will we request information about your account details by e-mail. However, if you receive an e-mail requesting you to provide or confirm such personal information, it is highly likely to be a fraudulent e-mail.

How to recognise fraudulent e-mails (so-called "phishing") and how to deal with them:

  • Unknown senders and the recipient's address: Check the subject and sender critically and delete this e-mail unread if necessary.
  • Attachments and links from unknown senders: Do not open attached files or deposited links.
  • Time pressure: Are you threatened with sanctions or reminder fees? Then you should double check this and, if necessary, contact us personally.
  • Typing errors and formulations: Fraud e-mails are often formulated colloquially and contain errors.

Therefore, please DO NOT reply to such e-mails and do not disclose any personal data, such as your bank account details.

Further information on the subject of "phishing" and how you can protect yourself against it can be found on the website of the Federal Office for Information Security (link).
