How to file a formal complaint against Belfius

  1. Step 1: Call customer service first
    Dial 02 222 12 02 and ask the agent to escalate to a supervisor. Note the agent name and case ID — you'll need them at every later step.
  2. Step 2: Submit a written complaint
    Belfius must acknowledge a written complaint within 5 business days under most national consumer rules. Send via certified mail or the brand's secure-message portal and keep proof.
  3. Step 3: File with the regulator
    Open a case with Ombudsfin at https://www.ombudsfin.be/. The regulator will not adjudicate your specific dispute in most cases, but the brand must respond in writing within 30 days.
  4. Step 4: Small-claims court or ombudsman
    If the dispute is under the local small-claims threshold, file at your local court. Most brands settle in writing before the hearing rather than send a lawyer.
