Parking issues in Mumbai Society 2019

I have 2 cars. Soc has alloted only 1 open parking space to me inspite of many open spaces available in the Soc. Other members with 2 cars have 2 open parking. Now there is a stilt parking of another flat who do not stay there and is vacant. I started parking my 2nd car there. All stilt parking flat owners have seperate agreement with builder since 35 years. Also the society recently painted all parking spaces with respective Flat numbers. I am parking this 2nd car in someone's stilt since last several years n now I realized that the Soc has been charging me fr car parking there. Also soc is separately charging parking maintenance to the actual flat /stilt owner. I feel this is cheating as there are several grudges involved. When other members park their car in someone's empty stilt they are never charged. A builder adviced me that stilt is the property of flat owner and not the society as per amendment to MHARERA. The flat owner may lease it out to you or charge you for parking. Not the society . Society is very arrogant in talking and dealing with me. I am a super senior citizen with severe paralysis and other health issues. I need one car available for any emergency. Society is falsely charging me and also the flat owner fr maintenance - double charge. All other stilt owners only pay maintenance charge wether they park any car or not. Pls advise all the means to to prove that this parking charges towards me is wrong. How do I get all my parking charges refunded from the society with interest and any penalty for harassment
