When I first sent an inquiry to them company in the Year 2018, they gave me a very quick and positive response. And Elena has maintained the habit of responding quickly. Communicating with her saves me a lot of time and energy. We trust them and keep cooperating with them till now 4 years, they never let me be disappointed.

Earlier this year my goods were held in the airport because of the covid. I was anxious and my client was mad with me. After knowing my situation, they rearranged goods for me and shipped those goods from another airport. Finally, I received the goods in time. I and my client were happy with it. Only after the Beijing epidemic was over did they retrieve the stranded goods from the airport. SYM team provides fabulous service to me and I’m so happy to cooperate with them.
