Thank you for taking the time to review and complement our after-sales service. We are, however, sorry that you are disappointed with our products. We always strive to provide our customers with the very best products at all times, but occasionally, even with high-quality products, issues can arise, especially when the products are over 13 years old. That is why all of our products carry a comprehensive 15-year guarantee, where there are no charges within the 15 years. We will contact you to arrange a site visit for one of our technical team so that they can carry out a product inspection. Once again we appreciate your feedback. Jennifer
