Of course. If an educational institution fails to attend classes after registration, it can negotiate a refund, but it will not be fully refunded. If no refund is given, consumers should negotiate with educational institutions and urge them to refund in time. If the refund is inconsistent, the educational institution refuses to refund, and the consumer can complain to the Consumer Protection Association about the educational institution, or bring a lawsuit to the court on the grounds that the educational institution is in breach of contract.
