Whistleblower System

We're happy to help

We support our customers personally, in partnership and competently and it is important to us to tailor our services to their needs in the best possible way. If you still have a reason to complain about a Tantum service, we will examine your concern carefully and promptly.

Depending on what your complaint is about, we will seek assistance from our knowledgeable and independent professionals to resolve the issue. The processing time depends on the complexity of the matter and may take some time. However, we will send you an acknowledgment of receipt of your complaint within a few days if we are unable to provide a direct response immediately.

There are different ways you can contact us:

You have the option to contact us either via our Contact Whistleblower System Form, which can be found under the “Contact Form & Addresses” tab, or send us your request by letter to the following address:
