Address:

Kanpur, Uttar Pradesh, 208001

My temporary connection was from 1/8/16 to 31/12/16.
after 31/1/17 it was the duty of the kesco to disconnect the supply and make the final bill but they didn't done it
on 25/2/17 they inspected my factory, they found everything ok accept that temporary connection agreement was over.
they are taking penalty from me under section 135
they have not done there duty of disconnecting supply and making final bill and saying i am guilty of section 135.
