What should I do if the property cancels all the remaining amounts in the owner's card?

According to the property management regulations, when dealing with the remaining amount in the owner's card, the property should be operated in accordance with the contract and relevant regulations. If the property cancels all the remaining amount in the owner's card, the following measures can be taken:

1. Check the contract: read the terms of the owner card in the contract carefully. The contract should clearly stipulate the rules for the use of the owner's card and the handling method of the remaining amount of the property. If there is a clear agreement in the contract, you can appeal according to the requirements of the contract.

2. Contact the property management office: contact the property management office and ask them why the remaining amount in the owner's card is invalid. Please provide contract or other relevant evidence to prove that the remaining money should be retained or returned to the owner. Please ask the property management office to explain and deal with this problem.

3. Seek legal aid: If the communication with the property management office is not clear, you can consult a professional lawyer or legal aid agency to understand your rights and interests and the legal actions you can take.

In the process of communicating with the property management office, we should keep a calm and rational attitude. If you have other evidence or statements to prove that your remaining amount should be kept, you can provide it to the property management office. If the above methods can't solve the problem, you can consider complaining or appealing to relevant departments or institutions to safeguard your rights and interests.
