Maintenance sharing issues

Hello Sir, We are staying in a apartment consists of 6 flats with three sizes (911,1132,1200 sq ft) and the apartment is not registered. While discussing how the maintenance cost should be shared by each of the flat owners, majority of them agreed to go with sq ft based calculation. I have raised concern to this approach as I own 1200 sq ft and the calculation is not fair for below reason. - Cleaning charges, electricity consumption charges, lift maintenance are used by all the flat owners equally so it is unfair to ask me to pay more. - I have also told them I am ready to pay sq ft based cost wherever it is applicable for example, building painting and repairs/maintenance. But they all started behaving weird, none of them answer to my question, they consciously corner and ignore me because I have difference of opinion and a concern with proposed method. Do I not have rights to express my thoughts and concern legally? Should all the other co-owners not listen and consider my concerns? They just stuck with this point, "let's go with the majority". I completely don't agree with this. It is like imposing and forcing someone else's thoughts. Person who runs the maintenance also taking sides and ignore my concerns which is bothering even more. Moreover no one is ready to talk to me on this as they have the majority. I am helpless. Please can you help me how would I come out of this?
