Landlord is not returning Deposit ₹1.25 lakh

I took a 1bhk house for rent in in 6th main road, domlur stage 2 (area approximately 300sq.ft very small ) on standard aggreement in 15 September 2018 on the monthly rent of 8000₹ . I gave landlord 125000₹ as deposit which is very high for that small 1bhk. After 11 month he started to ask 10000₹ as rent which is not as per our agreement (which is 5%) on paper . Somehow i talked to the broker ( middleman) and negotiate it to 9000₹ rent which is still more than 5% of initial rent. On 20 December 2020 i informed my landlord over 'whatsup' that i am vacating room by end of January 2021 or first week of January ,which is more than 1 month notice period as per our agreement and our broker was also aware of that notice period. On morning of 3rd February 2021 i handles all the keys to landlord . Now the issue is when i gave him notice period that time only i asked him to keep my deposit ready but when i handed keys to landlord he said wait 1 week for deposit money (125000₹) . After 1 week when i ask for money he is saying he didn't find the new tenant ,wait until he find new tenant . We don't have any aggreement like this but now he asking me to wait more . I have doubts about him he speaks in very ill manners way . I still have that original agreement with me and i also shifted to new house which is very close to old rented house and near the landlord shop. What should i do ? Shall i wait or file a complaint in police station. He speaks Kannada mostly and i don't understand Kannada because i am from Haryana ,thats why our mostly conservation happen on 'whatsup' so only whatsup chat i have as proof of notice period before vacating the house. The biggest mistake i did was i thought they are normal sincere person otherwise no one give in Bangalore give 125000₹ as deposit for 300sqt area without balcony or any other extra facilities.
