At YOUTH, our services are organized into three categories: pre-sale, sale, and after-sale. The after-sale service begins as soon as the TURN-KEY project is completed. Customers can contact us through various methods, such as email, phone, or instant messaging, to report any issues or needs in the after-sale period. We aim to respond to customer inquiries within 12 hours and provide a feasible solution, including any estimated costs, within 8 hours of receiving and confirming the customer’s request. For larger projects, our on-site technical service engineers will be available at the project site within 24 hours.​
