Tenant Rights After Vacating The Property

I was living in a rented apartment from 2016 Jan to 2018 Feb in a 2 BHK apt in Bangalore. Due to very urgent conditions I was looking for a rented house and came in contact with the landlord from a mutual friend. I paid an advance of 1 lakh with a monthly rent of 14200. The owner said he would need a 10% hike in rent every year and I said ok as was an urgency. After 1 year neither did the landlord ask for a hike nor did I talked. So I just kept paying same rent for the rest of 3 years. During my stay, I tried 3 times to get a rental agreement every time the landlord never responded and when I myself got the agreement printed he said he lost it so all 3 years no agreement was made by him. Rent and deposit paid online. I vacated my apartment in 2018 and asked him to pay back my Deposit. He never says he will not pay but it is already 2 and 1/2 years he has not paid but keeps saying will pay later and most of the time he doesn't make the calls. What options legally to get back my money.
