After a long time, it may not be possible to refund the accommodation fee of the training institution. There is no legal standard for accommodation fees, which shall be determined by both parties through consultation. Under normal circumstances, if you want to refund the fee after the training contract is established, there are several ways to protect your rights. First, it can be settled through consultation. If negotiation fails, you can report to the Consumers Association or the industrial and commercial department. If it still can't be solved, you can file a civil lawsuit. You can also file a civil lawsuit directly without consultation.
