Calcutta Electric Supply Corporation [CESC] — Huge billing for past 5 months

Address:

1/37 Paschim Putiary Colony, (Behind Unnayani Sanghya), Kolkata 700041

For the past 5 months, I am receiving a huge electricity bill. I have complained various times to CESC but they just didn't bother to reply to my complaints. I am now in a big financial problem due to this CESC burglary. Please take care of this matter urgently as CESC is not taking any action from their side.
