There are two property companies in a property area. What should the competent department do after receiving the complaint?

I can't give a more targeted answer because I don't know the specific situation. Answer only from the information provided by the question: 1. If it is a problem after the implementation of the regulations, it is necessary to investigate whether the way in which two property companies obtained property management rights is in compliance with the regulations. At least one of them does not conform to the regulations. 2. If the two enterprises have not obtained the property management right through legal channels, the existing property service contract shall be deemed invalid, and the owners shall be instructed to re-employ the property enterprise, and at the same time, do a good job in the coordination of the transition period. 3. If it is a complicated problem left over from history, it can be analyzed and dealt with in combination with the above two points.

The core of this problem lies in: the owners choose and employ property enterprises according to law, and the property enterprises must obtain the property management right through legal channels and sign the property service entrustment contract according to law.
