Tenants right to get re-fix rent

Hello, I am living in Noida on rented accommodation. I have a situation that since I have moved in this place, there were issues with fixation of doors, cabinets, electric sockets, taps etc. and in weeks time, seepage & leakage also started and all these conditions I had shared with relatives who were acting on behalf of landlady, they were always giving me some date and never turned up for repair but they were always there to collect rent and same day they were giving me another date for repair work. Now its been 12 months and not a single repair had been done and condition of house is such, that, I have left with no option but to change the accommodation. Question here is, I have paid rents either through online or sometimes cash, which I don't have any receipts. And for this month I am not paying since I have already paid them security amount equivalent to rent of 1-month. So is there any issues they can create because they seems troublesome people. Please advise. Thank you.
