You can contact our customer service by e-mail: firstname.lastname@example.org, or by telephone: +358 (0)9 47 655 655. Please note that giving us your case number makes processing the matter notably quicker (the case number can be found in our letter).
We will analyse the invoice and the error together with the client. If the invoice was sent in error, we will stop the debt collection. If the invoice is found to be well-founded, the debt collection continues. However, we will notify you of the result and explain how we reached the decision in each case.
