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.

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.
