In the month of may my bill was of 540 rupees, in the month of june it was of 1200 rupees and in the month of july all of a sudden its exceeded to 5680, we are living in 1 bedroom flat, the only decices running are 2 fans, 2 tubelights, 3led bulbs, 1 ac thats it. And all of the sudden my bill exceedsto tripple of its amount? How is that possible, and now in the month of august i have recieved the 9860 rupees amount of bill. How is this even possible, the metres in my building are fitted by bses only, that what is my fault in it? One of the reading takers once told us that if you want we can do something with your metre so that you will recieve lesser amount of bill, but i denied, and now i am receiving this 9860 amount of bill. Other neighbours are recieving bill oh 40 rs, 100rs 450 rs. Thats it. What is this system?? And how is this even possible??
