Corruption happening within RWA

I the society where I am staying currently RWA hosted meeting just once this year that too they left in between as questions relates to financal records were asked, they don't want to share financial details or Audit reports with the residents. After this incident, the previous association are asking only flat owners( who's names are in the agreement) should join the meeting and we don't feel it's necessary to share financial details with everyone. After doing some digging I found out that they are awarding contacts for amenities repairs unfaithfully, they are not taking multiple quotes , even if in some case they are taking quotes they are leaking it to the only contractor who is doing all the jobs at a very high price... Much more than the market price... The condition is soo bad that first he is doing the work and later he is providing the quote and it's get approved and he gets paid. Recently our parking work was also awarded to another contactor who didn't complete even 50 percent of the work and run away with 95 percent of the money.. (24 lakhs) Another contact was doing where the area is hardly 2000 square feet but the contacter is paid for 3260 square feets. Problem here is I can't fight alone and everyone seems to be fine here with the corruption happening as if everyone is part of it.. I don't want to hide the apartment name here ..it's Unicca Emporis in Bangalore. Can someone please guide me here what to do.? And how can I stop this.?
