Dumb chinese people

I'm not saying that all chinese people are dumb, but I recently received a package with pretty much only one component in it, while there were supposed to be two and batteries, as well as cables. HA! "Will send back. Customer guarantee." or they probably might say something like "you satisfy product, available with wireless and receive". Funny, but seriously, it's true. Chinese people, do they really care about the product?! I bought the product because other products which are like it would cost me about $90 or more! These days, many cheap things exist on sites like Amazon, and what seems like so many that are borderline need/want.
