I joined I am doors and windows on March this year. I feel that the after-sales service of the headquarters is OK. If you have any questions, you can contact the after-sales staff to solve them. The handling is timely. Generally speaking, the headquarters has customer service department, Yibo, multiple departments of the order receiving Department assist our distributors to issue orders, and the delivery time is relatively short. Overall, I am very satisfied.
