1. Negotiate a refund with this institution, and both parties will make concessions to reduce the time and money costs brought by litigation.

2. If no agreement can be reached, you can bring a lawsuit to the court to show the losses caused by the agency's breach of contract, request the court to judge the agency to return the deposit, and you can ask for part of the liquidated damages.

3. It is unreasonable for the institution to refund but deduct money. Even if there is no receipt, the organization must have proof of your payment, and you can't deduct money just because the documents are lost.

Hope to adopt!
