Repayment of advance for rental house

I was in a rented house in Trichy and paid Rs.50000/- towards advance to the owner (lady) who is in Pudukkottai. 6 months in advance, I have Informed her that we will vacate on 31.03.19. We have cleaned Septic, water tank and the house also cleaned, after the household goods are taken. When I asked for the advance paid, she is asking is there any rule that she has to refund advance on day of vacating. And also she used unparliamentary words, which were recorded in my phone. Kindly inform what is the action to be taken to get back advance amt paid.
