Most training institutions will delay the time for various reasons, because the promise of refund is generally time-limited. After overdue, the other party refuses to refund the fee on the grounds that it is overdue. Here, the lawyer reminds everyone to try to keep the communication record of applying for a refund.
Training fees can be refunded within a reasonable range, even if there are overlord clauses in the contract, such as whether the contract is signed or not, it is not protected by law. I suggest that everyone must learn to protect their legitimate rights and interests by legal means when their legitimate rights and interests are damaged. If negotiation fails, you can entrust a lawyer to intervene.
