Unregistered Apartment association trying to take over assets

HI Sir, I am an owner of a flat in Bangalore. Builder has not obtained fire NOC , OC and have not provided KHATA to flat owners. Builder has registered the DOD of apartment under Karnataka Apartment Ownership ACT 1972 but builder has not registered Apartment Owners Association under Karnataka Apartment Ownership ACT 1972.Now there is one committee in our apartment complex who is trying to take over of Apartment complex assets and management from builder and same committee asking flat owners to pay maintenance amount and some other money to so called association as told by that committee. Builder has not provided OC , and KHATA to flat owners yet and without getting all these that committee is trying to take over and passed the resolution for same in some GBM meeting with vote of only around 10 % flat owners. Now my questions are: 1. Can that unregistered committee take over assets and management of apartment even when builder has not completed many legal paper work like OC , KHATA and NOCs and also builder has not completed many of ifra related pending work on society.? 2. Can that unregistered committee ask flat owners to pay maintenance amount and other money to so called association? 3. Can that committee pass any resolution related to society and bound flat owners with same? 4. If that committee cannot do any of the above then Where can i file complaint about that unregistered association to stop them from taking over of assets and management of society, where to file complaint ? Please help we are in very bad situation as of now.
