If the property is not maintained, where should I complain about water seepage on the external wall of the house?

Legal analysis: For the general problems of the property management company, the owner can complain to the employer's owners' committee (or developer) and be responsible for making corrections according to the contract. For major problems of property enterprises, owners can complain to the property management section of the local housing authority, which is mainly responsible for accepting complaints from owners' committees or developers; Do a good job before the complaint, try not to take the form of oral complaint, and try to submit it in writing; Look at the property management agreement signed with the property management company before submission. Where the property management company failed to fulfill its responsibilities, the evidence should be complete.
