House Owner — Not refunding security deposit

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I had rented a flat in Civitech Sampriti, Sector-77 Noida.The house owners name is Ashok Kumar ([protected]) and the broker was some Rakesh([protected]).The broker was a complete thief and he passed on wrong information to the owner during our vacating the flat.He was telling that they will charge 50 Rs for each nails on the wall.He also wrongly gave feedback to owner that walls are dirty and needs re-painting which require 15000.His sole motive was to extract money from owner.Owner was also of the same kind and he is not refunding us our hard earned money.He is not lifting the phone and making silly excuses.Dont know where to go to get my money back.
