If the remedial class does not refund the money, it can be prosecuted through negotiation between the two parties, institutional arbitration or civil litigation in court. First of all, the parties should write an indictment, and then submit evidence and the indictment to the court with jurisdiction, file a case, and pay legal fees. After the court makes a judgment, the judgment has legal effect. If the other party refuses to perform, it may apply to the court for compulsory execution after the judgment takes effect, and the court will directly seal up the other party's property. There are several solutions for training institutions to violate the original agreement: 1. Negotiate with the institution for refund, and both parties will make concessions to reduce the consumption of time and money cost brought by litigation. 2. If no agreement can be reached, you can bring a lawsuit to the court, explain the losses caused by the institution's breach of contract, request the court to judge the institution to refund its deposit or tuition fee, and you can ask it to compensate part of the liquidated damages. 3. Without documents, it is unreasonable for institutions to refund money but deduct it. Even if there is no certificate, the institution must have its own proof of payment, and it is not possible to deduct money just because it has lost its certificate.
