What I said before was quite good. I gave money to distribute packages and things. Then, I gave 3000 yuan for teaching and things, and then I gave a card for free unlimited lectures! Now they have closed all the courses! I'm no longer in charge, there's still one subject I haven't studied, and they haven't started classes! No refund! Many students in the group have hardly studied, the money is not refunded, and the courses are not opened! Then kick everyone in the group! Call and open your mouth to curse! This kind of person has extremely low quality!
