Colive — Unauthorized charges

Address: 3rd Cross Rd, Kaveri Layout, S.G. Palya, Bengaluru, Karnataka 560029

I was staying at Colive Tornio, Bangalore. I raised a notice to vacate the place on 1st December and vacated on 31st December. I had informed the property manager to adjust the rent from my deposit as the deposit was 9k and rent was 7.8k. I did not even want 1200 back. But after a few days I have received a mail from Colive asking to pay them 4.5k which includes separation charges and 2 months of electricity bill, which is completely absurd. If I have raised a notice period of 1 month then what is the point of raising a motnh's notice period and why should I pay for 2 months electricity when I have not even stayed there. And moreover the rent is shown as 10.7k instead of 7.8
