We went to the class only once. Becaus one of important family member is very sick. I have to go back to my country. So I want to cancel my class. But they not agree, and they charge me$400 for one lesson. That is very immoral and inhuman. I told them I will publish all my experience to all social networking sites. And the admin said do as you like. They are very rude. And they only care money, no respect. Seriously shocking and disgusting!
