Refund of my advance payment from the proprietor

Hello, I have paid an advance of 5L to the landlord for the lease property. But the total lease amount was 12L. But before paying the balance amount I again visited the house to check with the pending works that has to be completed before I occupy the flat. But the landlord denied and demanded me to pay the remaining amount. But this instincted me to check with the other tenants in the apartment, there I came to know that this landlord will be arrogant and rude and moreover there was no basic facilities like metro water and sewage system. So I told the landlord that I am canceling my agreement and asked him to return my advance payment. Initially the landlord asked time to refund my money and his reason was the money will be refunded as and when he gets the other tenant or by selling the flat. But the date he mentioned to refund also gone but I did not receive my amount. So I kept calling him but he went unanswerable, so i visited the flat wbich was alloted to me to check if any tenant occupied the same. I was literally shocked to see the landlord himself has occupied that flat. i was exremely anger but controlled my emotions and asked my money to return back immediately. thetefore he asked me to visit his office and gave a post date cheque. So I agreed that and came back home and not disturbed the landlord until the cheque date comes. But he was not answering my calls, so I informed him over text and deposited the cheque 4 days after the cheque date. The very next day I received a message from bank saying that due to insufficient fund the cheque got bounced. I was extremely panic and I am helpless, clueless. So I asked the landlord regarding this but his reply was horrible, rude, arrogant, reckless and very threatening. So I request the officials to help me out how I should proceed with this? Will police accept my petition? Else what is the procedure to go further?
