Maintenance charges in apartment

Sir, My name is N C Manjunath Vibhu, Retired from Postal Department. I am the one of the Owner of 3 BHK Flat in Suprabath Shreem Breeze Apartment, Vasanthapura Main Road Near Kumaraswamy Layout, Bengaluru 560111. In my Apartment Maintenance charges is collected on Super Built up Area with the difference up to 85% between the flats. Rs 8,470 to first 2 BHK and Rs 15,671.00 to last 3 BHK Flat on SUPER BUILT UP AREA of the Flats per Quarter.( I am paying Rs 14,831.00 per Qtr) Total difference between the Flats is 823 Sq Ft. ( First 2 BHK 968 Sq Ft & 1791 last 3 BHK) Our Association is Registered under Karnataka Society Act 1960 but now Committee says as per Section 6 and 10 collection of MC on Super Built up Area is correct. There are 44 TWO BHK Flat and 28 THREE BHK Flats. Nearly Rs 28,804.00 is paid EXTRA / MORE by last 3 BHK flat Owner. In the name of MAJORITY all our claims are snubbed. Collection of MC started in the year 2020 by the Builder & same is continued by Association. No resolution is passed till today on the method of collection of MC after builder left. My argument that Committee is collecting more from us & profit distributed to other owners which violate Section 3 (g) of 1960 ACT is not accepted. Even Actual Calculation prepared & given to Committee for fixed charges to all 2 BHK and all 3 BHK Flats rejected. Only I am fighting for revised method. If I question the area wise collection all 2 BHK Owners shouts and pounces on me in meeting. Committee also not able to convince 2 BHK Owners for revised method. I am giving the representations but in vain. I requested for the actual expenses incurred for my flat & of the flat paying Rs 8,470.00 every month but they are not ready because they know it will be very less than I am paying ( Rs 14,831.00). Therefore personally I want to challenge the method of collection. But, other 3 BHK owners are fed up of rude behaviour of 2 BHK Owners and keeping quiet. I request you to guide me and give me your kind opinion on this issue to reduce the charges paid. I am ready to give any further information required. Thanking you Yours N C Manjunath Vibhu
