It cost 4980 yuan last year. At first, I couldn't remember when the three coaches told me they didn't want to go to school, just subtract the hours they had attended. Unexpectedly, the child decided not to go to school after a few classes, but the school said it was not someone else's school, which was written in the contract. I didn't read the contract at that time, thinking that the coach said it would be ok to return it. Who thinks there is a hole in the contract, and suggests that anyone who wants to go to Acer should go?
