Is Zhang Qu Science and Technology (Beijing) Co., Ltd. a fraud company?

Is a liar. They cheated me out of 3450 yuan and haven't paid it back yet. And asked me to give them 3450 yuan. Dear friends, don't believe it. The first order they give me will usually give you counter money, but the second order will start to cover your money desperately. Now I have covered 3450 yuan, and the other party is still covering my money!
