Issues with other owners in Flat community

Hi, I am one of the owners, a woman, in Apartment community, Chennai of 8 flats with 2 blocks containing 4 flats each. I live abroad and have tenant at in my flat. There is no association formed from the beginning. When there are issues in common amenities or common issues impacting both the blocks, both blocks look into it together. if there is any block specific common amenities issues, respective block owners look into it. My flat is in B block. For any common work/issues in B block, there is no discussion occurring involving all 4 owners in terms of scope of work, what kind of solution needs to be applied for the scope of work and choosing the vendor. 2 of the owners dominate and they want to implement whatever they like to. out of these 2 owners, 1 owner is the mouth piece for other and supports whatever this owner does blindly. Even if he participates in the whatsapp group chat, it is only for accusing me and praising this other owner. These 2 owners had been dominating and when I ask them to have discussion involving all 4 owners and take inclusive decisions. It is not just difference of opinion but there is also no cooperation for any maintenance that needs to be done in the apartment or for common amenities. Issues are getting pushed until it becomes emergency and pressurizing me as if I am not cooperating. Their expectation is I need to just pay my share of expenses in what ever this owner decides to do right from finalizing the scope of work, approach and vendor. In addition to above concern now, these 2 owners do not maintain any decorum in the group chat and have accused me in 2023 that I betrayed them getting lot of money for the common work that was completed in 2019 with the consensus of all 4 owners right from scope of work, cost and vendor. Even for any common area issue that has got nothing to do with me or the work completed in 2019, they tag it to me as if I gave them poor quality work ad expect me to fix the issue and take care of entire cost. They have also threatened me several times in whatsapp group chat for no valid reasons stating they will give police complaint. They bring in unnecessary topics in forum which is no way to related to issue in hand and blame / tease/ humiliate/ accuse/ threaten me. This has been their attitude since 2019. Even last year, they did a common work without agreement from all 4 owners and I still paid my share saying that would be the last time i will be providing money when all owners consensus is received. Now again in 2023, same issue has repeated and I have not provided my share of expenses. I had also communicated to them before starting work itself that unless and until all 4 owners consensus is arrived, I would not be able to support. Now, after completing the work, when i refused to share the expenses, they are threatening me that they will block water and drainage connection of my flat. I shall post remaining portion of the query in comment section, if possible. Thank U
