Before confirming a visit
Record the business name, company number, address and contact details. Check that they match the documents you receive. Describe the problem without forcing the door: some faults need an on-site examination.
Understanding and keeping the agreement
Request a clear document describing the service and its conditions. Ask for explanations of replacements and changes before agreeing. Belgium's FPS Economy recommends a complete written offer before the intervention. Official emergency repair advice (French).
If a problem occurs
Keep messages, documents and relevant photos. Send the business a written complaint explaining the disputed facts. ConsumerConnect helps report suspicious practices and identify suitable next steps; a report does not guarantee reimbursement. Contact the police if you face threats or immediate danger.
