Is Sichuan Southwest Aviation College all right?

It's really arbitrary charges. I only paid more than 10 thousand at the beginning of school When I went to study, I said I paid more than 10 thousand. When I signed up, the class teacher had not received our invoice. At present, the invoice in hand is only more than 8000 yuan. Now that the second semester is about to start, I am required to pay more than 2,000 yuan, saying what the book fee, tuition and accommodation fee are. The charge is very high. When you went to school, you said to look at the dormitory, but they said nothing. It sucks.
