The store you bought has signed the acceptance certificate, but the door is broken and has not opened yet. Is it the responsibility of the real estate company or the property management company?

If you don't sign it, find a real estate company. If the problem of community security is vandalized by lawless elements, you should find a property company.

If it's only because you didn't find the quality of the door is good when you checked and accepted it, it's not someone else's damage, then you'll be responsible for it yourself.

Now people are afraid of being responsible, and they want others to be responsible if something goes wrong.
