What should I do?? Do I have any right? What actions I can take in my defense?

I was about to go on a rental flat on 3rd March 2024 in Mumbai. We shifted all of our belongings over there. Agreement was about to be made as there was a sudden fire catch at the advocate office so the agreement delayed. We gave 1Lakh INR deposit and 2 months rent decided as 26500/- per month for the March and April 2024. Other 4 months rent cheques are also with that licensor; but post dated. But, these building has so many issues after we came here almost everyday in this building there is no water supply and electricity supply for 8-10 hours and it's very difficult to manage. This building didn't get the OC as well. Building's construction is so poor that you can't even insert a screw/ nail in the wall as it gets damaged severally, even though this building is constructed newly and many floors are remaining to even built. We haven't sign the agreement yet. But, as per verbal agreement we assured that we will stay for 2years. But we want to leave as soon as possible. We discussed our matters with the landlord and they are mentally pushing us and giving threats to the sign the agreement but we denied. We talked about this on a call. Later, she called us and said we have an option to vacate this place it can happen. Now , she sent a legal notice to vacate the place and demanding one month rent as compensation, want us to re-paint the whole house even though we haven't lived here for proper two months, and demanding drafting charges of agreement of 4100INR.
