Atrocious rates in the winter time. I have no cent...

Atrocious rates in the winter time. I have no central heat and air and no heat in the apartment. It's an older building and the owner/landlord won't fix it so I use a small heater in my bedroom. I have called questioning my high bill and only get numerous reasons why my bill is so high. Last year I froze even with 6 blankets and a comforter on and putting a towel under the door. I unplug everything that is not needed to be left plugged like refrigerater. These high bills need to stop! I'm on disability with a limited income and I start to panic every winter because of this. My bill went down some because I froze last winter and that is just not right!
