1. Re-communication and written notice: further communicate with the other party and send a written notice to it, clearly pointing out its breach of contract and the amount of compensation you require. The notice states the specific facts and basis of breach of contract and requires the other party to solve the problem and make compensation within a reasonable period of time.

Second, check the terms of the contract: carefully check the terms of the contract, especially those related to breach of contract and compensation. Determine whether there are provisions that clearly stipulate the liability for breach of contract and the way of compensation. If there are clear breach clauses and compensation clauses, corresponding legal measures can be taken according to the contract, such as claims and liquidated damages.

3. Collecting evidence: collecting evidence related to breach of contract and loss, including contract documents, communication records, payment vouchers, photos, etc. These evidences will help you prove the other party's breach of contract and the losses you have suffered, and provide them to arbitration institutions or courts when necessary.

Fourth, hire a professional consultant: If you are unfamiliar with legal affairs or uncertain about how to deal with breach of contract and compensation, you can consider consulting a professional lawyer or legal consultant. They will help you assess the situation, provide legal advice, and negotiate, mediate or litigate with each other on your behalf when necessary.
