Faulty, damaged or incorrect goods
Email contact-us@klifex.net with your order details and a description of the problem. These claims are separate from change-of-mind returns. Where we are responsible, we bear the required remedy and return costs. Installation alone does not remove mandatory defect rights.
Your legal rights
Applicable statutory rights take precedence, including EU/EEA and UK withdrawal rights and legal guarantees. Necessary inspection does not remove a statutory withdrawal right; deductions for excessive handling must reflect an actual, evidenced loss of value.
