What is the authority of an unregistered housing society? How does unregistered society maintenance

Respected Sir, I reside in a colony maintained by an unregistered society, whose members are chosen by the residents. The society collects two types of maintenance fees: one for electricity (since no individual meters are installed, the society collects a fixed charge from each house and pays this to the electricity department) and the other for security, cleaning, and general maintenance of the society. My house is currently under construction, yet the society is charging the same maintenance fee as for fully completed houses. Disagreeing with this, I stopped paying the maintenance fee. As a result, they have disconnected the electricity supply to my under-construction house. What actions can I take against the society for disconnecting my electricity, and what actions can they take against me for not paying the maintenance fee? Additionally, the society does not audit its accounts and collects approximately 2-3 lakhs in cash per month. Please advise me on how to proceed in this matter. Thank you very much
