Fraud dealer cheated money and now denying to give

What I need to do , I am a girl and I am cheated by a fraud dealer who took cash from Me that he will let me flat in Gaur city , noida extension , greater noida ( I was looking flat on rent ) He said that he talked to owner of the flat , and he sent our ids , owner will come to the place and will give keys of the flat after 2-3 days. I waited for 15 days , and he keeps on cheating that owner is in hospital , someone from his family is in hospital , I trusted him till that Time. Luckily I got owner’s number from that site where I found the dealer’s number , and I called to owner he said that flat is occupied 1 week back only , he got my ids also but he didn’t get my money. And that dealer allures 3000 rupees advance token amount from me by saying that he gonna give to owner. Now he is not replying , he blocked my number , I am a bachelor , and he is now denying , Yesterday I talked him badly and he said that u talked badly now I will not give . Bring police if you want.i am planning to file a police complaint , Pls suggest what else can I do
