Property is particularly fierce.

1, communicate with the property management company and ask it to negotiate with the upstairs;

2. If the property company prevaricates, it can complain to the property company, specifically: complain to the headquarters of the property company or complain to the property management department of the Housing Authority, the competent department of the industry; You can also refuse to pay property management fees, water batteries, elevator fees and other expenses on this grounds.

thank you
