Your purchase is covered by the Sale of Goods Act, including the lack rules. This means that the consumer has a 2 years warranty. You can either have a faulty product repaired or replaced, get a refund or reduction in price depending on the specific situation. Of course, it is a requirement that the complaint is justified and that the defect is not caused by incorrect use of the product or other injurious behaviors.
You must complain within "reasonable time" after you have discovered the defect. We recommend that you claim it as soon as possible. You can complain by contacting us via email: email@example.com. Depending on the specific situation, you will receive further instructions.
If the complaint is justified, we will refund a reasonable amount covering the shipping cost. Otherwise, you must bear all costs of transport, including our freight costs for returning the item after the investigation. Remember that the product must always be in good packaging and to get a receipt on the shipment when handing it over. You bear the responsibility of the package/goods until our receipt. So keep the postal receipt and tracking number. We do not accept packages sent COD (cash on delivery).
