Aliexpress protect bad companies and not the buyers.
There are a lot bad companies here like:
East Dragon Electronics Co., Ltd
ADDRESS:4E Aozhihao Complex Building, Xinzhou 4th Street, Futian District, Shenzhen China,518048
If you have a problem and make a dispute, it's sure that you'll lose your time and your money.
There was a lot of complaints here but Aliexpress ban all with negative comments like my friend from Greece which paid about 300$ and never received the order.
As you'll see, this comment will not exist in a little time because Aliexpreess will ban me as it does to all with negative comments, even they could to communicate with all us and try to solve our problems.
The only way is to inform all forums in world to avoid buying from Aliexpress and Alibaba.
