This buyer is a liar. He buy a item, after receive the item,he said the item does not have the function he wants.
But seller's ebay listing never said this item has that function .

He said if the item does not have that function,seller need to specially write it out,otherwise seller are deliberately mislead him.
WTF,seller already says what is the item,and what can it do, why would seller have to say what it cannot do?
If we have to to that,the listing page would be super long, we have to say it cannot make you fly to the sky, it cannot change your gender.it cannot be an alarm .........?

So if you are a male,and you deliberately go to female toilet to Peeping women，when police comes，you can say the female toilet signs needs also write “Not for male” under it，otherwise it is misleading？ What kind of logic is that？！

Make sure you be careful with the buyer using the email that use "@sbcglobal.net"
This is Organized crime. We have get a lot of bad buyer reports,a lot of bad buyer are using @sbcglobal.net email.
They seems to sign up a lot of ebay account,buy things from seller,and make a lot of issue to seller. And open unfair cases.
They never admit the obvious mistake they have made,that means they did that deliberately .
