Address:

Cesc,kolkata, Kolkata, West Bengal, 700002

Dear sir
Myself, ram sagat razak, 1/4/d kc road, kolkata-700002. My customer id-[protected]. I have been charged with consumption of 9797units for april 2019 which is completely absurd and vague. There must be some sort of mistake/fault on the part of cesc. My complaint docket no is 21945192
They sent me a bill of rs. 83620 which is way beyond our imagination. Our usual consumption trend is around[protected] units per month. But this hefty amout of bill is impossible for us.
Please look into this matter at the earliest.

Thanks in advance
