Flat Owner — Not refunding security amount

I lived on rent in a 2BHK flat (Q203, Madhuvanti, Nanded City, Pune) for three years. Few days back my flat owner asked me to vacate the flat as their relatives wishes to live in this flat. I left the flat on date which they decided. Later I did painting and cleaning and ask owner to refund the security amount Rs. 35000. then they tried to deduct the security with multiple reasons for which I gave them multiple documents/proof. Later they said painting and cleaning quality is not good, our wardrobe and drawers condition is nor good and with these reasons they are trying to reduce the amount by 25000 and will refund only 10000. Please suggest what can be the best way to make a complaint against this.
