Is it reliable for Zhongcheng Legal to refund the deposit?

Hello, after inquiry, it is not reliable for Zhongcheng Law to refund the deposit. Because in legal work, the basic fees they charge, that is to say, the part that B collects when helping you, no matter whether you win or lose, whether you have done something for you or not, they will not refund this part of the money, but will only charge extra fees, which may be part of them, and they will only refund part of it, and others will not.
