Can I call the police if the property doesn't handle the problem?

Legal analysis: the property can't report to the police if it doesn't handle the problem, but it can sue and ask the other party to bear the liability for breach of contract.

Article 577 Where a party fails to perform its contractual obligations or fails to perform its contractual obligations in conformity with the contract, it shall be liable for breach of contract such as continuing to perform, taking remedial measures or compensating for losses.
