What should I do if the management of the underground garage in the community is chaotic?

Garage can't be inhabited, on the basis that it can't be designed according to the living function when designing garage. Just like what is registered on your real estate license, the function of your house can only be living. If it is a company, it is strictly illegal. The solution is to negotiate with the property. If the property doesn't work, we can unite to copy the property. You can also go to the Housing Authority to complain that the property company lets people live in the garage, which affects safety.

2. If you don't invoice, you can call the tax department and complain about them. This is easy to handle, and now it is cracking down on tax evasion.

It seems that your property is not so good, depending on the reason. If the property fee is too low, there seems to be no better way. If the property fee is not low, you also have the right to check the accounts of the property company, and their fees should be made public regularly.
