Unethical practice of denying parking if the vehicle is in another residing family members name.

We have been living in this society for 24 years. And have owned a car since 2014 and allowed to park in the same society. In the year 2023 I changed my car. As a diligent law abiding member of the society I intimated the society of the change of vehicle number. The secretary in charge refused to accept my letter stating I am not a member. The member is my maternal uncle on whose address I have been residing ever since 2000 with my aadhar, pan card, driving license, passport as well as the said both old and new vehicle registration being of the same address. The society in the September 2023 brought in an agenda to deny parking to us and the same was thwarted by few members in the meeting. I was told that there was no resolution that was passed on the AGM. However to our surprise and shock the society sent us a notice 6 months after the AGM on March 2024 intimating the cancellation of our car park. Is this action legit? Post which my maternal uncle who resides in UAE tried to give a letter to make me an associate member. The secretary has denied to accept the letter stating only the members son, wife or parents can become an associate member. Which I believe is false. As I have read that parents, children, wife, brother, sister, niece and nephew can be made an associate member. Kindly let me know if the society is in the right or if we can take an action against the same?
