This guy never read listing，the problem he told us is just because he don't understand how to use the item，so he think the item has problem. We explained，and told him how to use it. He said we insult him. This guy is crazy sensitive.

The item you ordered contain the function you want，but you have to turn let function on(the default setting is off). We told you how to turn on,you call us rude people. Hey,you don't know something,people teach you how to use,does not mean people say you stupid.

So you are stupid asshole,go fuck yourself,that is an insult .

Do not sell things to this guy,he will open case only because his sensitive heart. When he don't know how to use your item,you cannot teach him how to use, that will embarrasse him,he think he is smart,he knows everything,so he will open a case to ebay say you insult him.
