Missing Delivery Return Eligibility If you wish to return a product for reasons not related to defect or error (e.g., change of mind or dissatisfaction), the return shipping costs are the customer’s responsibility. Any preferred courier may be used, and once the returned item has been received and inspected, the refund will be processed. However, if the product you received is incorrect, damaged, or defective, the return is completely free of charge and the refund is 100% guaranteed. In this case, please send clear photos and a short video showing the issue to info@benitronica.com. Each customer can also request a return directly from the product detail page. However, we strongly recommend contacting us by email or through customer support immediately after submitting the request, so you can provide the necessary photos and videos of the product to speed up the process. Our customer service team offers a dedicated real-time assistance session for every customer after purchase.
