Landlord harassing me

Hey guys I am 28 F living in gurgaon since November in a rented property. Today I have given notice to my landlord that I will be vacating the premises by March end. However she has not returned the security of previous tenants who left so I have asked her to adjust my rent for March from security and I will pay whatever additional amount is needed. She initially shared a rent agreement but the dates on the agreement were wrong so I asked her to update it and reshare which she never did.FYI she has clearly mentioned while I was joining that there's no lock in period and we just have to give her a month's notice and the agreement also doesn't have any lock in. I have a soft copy of her agreement as well as proof on chats where she is harassing me by threatening me if "I want to fight with her". I also have chats and audio calls from other tenants mentioning she hasn't refunded her security. One of the old tenant is also willing to give a witness on call that her security is not refunded, if I take a legal action. Can someone please help me? I am quite concerned about my personal safety as well as my belongings.
