Harassment By Broker/Landlord

Hi, I rented a house via broker Since March 2023. The rent is 25000/per month. Deposit is 100000. All these are mentioned in agreement. Brokerage agreed was 1 month rent. I have paid all the dues on time. The broker is harassing me for last 1 month by Saying that agreed brokerage was 1.25 Lakhs (Even when the signed agreement it is mentioned that the Deposit is 1 Lakh). When I pointed this out they have sent an eviction notice over email stating that we are not responsive to their demands. Further they are asking that 1 month rent needs to be cut from the Deposit as the lock in period of 4 months has not passed along with 15 days rent for Painting Charges. All the transactions are done online, so proof is available for the same. What should I be doing? Should Is Send a legal notice to them and file complaint.
