Training institutions stipulate in the contract that the fees cannot be refunded by "format clause" and "overlord clause". There can be an agreement between the training institution and the trainees, but the agreement cannot violate the relevant laws and regulations. Students or parents can provide payment basis and written materials to coordinate the refund. The so-called consumer complaints refer to written or oral objections, protests, claims and requests made by consumers to solve problems due to disputes with operators for daily consumption needs.
