By law, collection costs must be paid if a case has already been transferred to debt collection. If you have paid the original invoice before the date when the collection letter was sent, you do not have to pay collection costs. If you have paid the invoice on the same day that we sent the collection letter, it is considered that debt collection has begun and you must therefore pay collection costs. If you believe that you should not pay collection costs, please contact us without delay so that we can clarify the matter. In such a situation, please be prepared to supply us with precise payment information.
