I am a resident as a tenant of 301, Third Floor, Bait Ul Humd Apartment, Street No. 10 Azeez Bagh Colony, Shaikpet 500008. My all bills of the rented apartment is clear before time. But every day the electricity supply of my apartment is out for 3-4 hours whereas the supply is there in the whole building, streets, and building lift. I am facing this issues from past 20-25days.I and my family members reminded the landlord multiple times but he doesn't answer the call nor give any reply to the complaint. He is mentally harassing me. Kindly help.
