Calcutta Electric Supply Corporation [CESC] — Excessive charges this month

Address:

CESC House,Chowringhee Square

Sir/madam, i am gita bandhopadhy, consumer number is: [[protected]], customer id is [[protected]] in the month of april my electric bill is about rs, 1540. But in the month of may, it amounted rs, 4310, this is extremely outrageous since absolutely no appliance has been added since the previous month. From 1540 to 4310 is a huge leap. Kindly look into this issue asap. I would be highly be obliged to you if you accept my proposal.
Failing which states in consumer court.
Your’s faithfully gita bandhopadhy consumer number is: [[protected]] customer id is [[protected]]
