📨 Wrongful collections letter — how do I respond?

Direct answer

On wrongful collections letter (wrong amount, already paid, or too high): (1) Check the claim: calculate maximum allowed collection costs at schuldinfo.nl/incassocalculator. (2) Reply in writing (email + post) disputing + why. DON'T ignore — costs accumulate. (3) Pay only principal + statutory costs: notify in writing that you paid. (4) Complaint to agency: no response within 2 weeks to creditor, then NVI dispute committee. (5) Suspect fraud: Fraudehelpdesk. Collection agency may NOT seize assets without court ruling. Threatening bailiff without ruling = deception. Complaint at ConsuWijzer.
