We are extremely sorry that your attempt to contact our Customer Service is unsuccessful.  The time of promotional campaigns and sales is a period when there is an increased number of email requests, chats and phone calls. We work hard to provide comprehensive and satisfactory answers to all requests. While we make every effort to resolve requests as quickly as possible, the response time or waiting time on the hotline may be extended. We apologize for any inconvenience. We ask for a moment of patience and understanding - we will not leave anyone without an answer.
