An appeal related to errors in an invoice should be made in writing to the party that issued the invoice. This will be either a toll service provider or a toll charger.
If you have signed an agreement with a toll service provider, this agreement will specify the rights and obligations applying to you and the toll service provider in question. Individual toll transactions for vehicles without an agreement will be invoiced by the toll charger that owns the toll station where the toll transaction was generated. In such cases, the rights and obligations applying to you and the toll charger respectively are laid down in the Norwegian Regulations relating to the Payment of Road Tolls.
Disputes between a toll service provider / toll charger and a customer regarding invoices are subject to the provisions of the Norwegian Disputes Act concerning mediation and procedure in civil disputes.
You must send an application for an exemption to a toll charger that decides whether the exemption can be granted. Such a decision can be appealed to the Norwegian Road Directorate.
