Does anyone know Shanghai Double Click Information Technology Company? Is the nature of consulting firm reliable?

It's unreliable, the play is unreliable, and you don't even know how deceptive they are? The salesman told you that you could find out the details of the guests. After you pay the money, you will find that the specific information is only 20%. Their customer service is not online all the year round, telling you that only 20% of the information is normal. The key is that when you develop this 20%, 60% of the information rooms are fake and 20% are freight forwarders. Although double-clicking on the information of the promised freight forwarder can block it, I just started to do foreign trade and used theirs, wasting money and energy. Extremely harmful to people
