Have you ever used the intermediary service of Su Shun Express?

I am the courier of SF Express. This one you're talking about is called payment collection Service. But as a buyer, it is risky. Generally speaking, as a door-to-door salesman, I can only check whether the outer packaging is in good condition. I have to sign it first, and then I'll show you what's inside after I pay. If it's not what you want or nothing. Then you have to contact your seller. The courier company won't contact you. You are advised not to use this service.
