Kerala State Electricity Board [KSEB] — wrong tariff and wrong billing

Consumer number:[protected]
Consumer name: subash n
Section: kozhinjampara
I went many times direct to kseb kozhinjampara and requested for tariff change from construction purpose to normal. And i submit the written request as well on around 1 year before and after site visit also they have not changed the tariff. And i used to followup many times. I do not understand whats their problem. Since i have completed all construction on my newly constructing home and due to personal things no one is staying in that home still.
Kseb kozhinjampara staffs are so arrogant and misbehaving staffs. Its been 1 year i am following for the same and i am paying extra un necessary amount on bill for their own mistakes.
I am hereby requesting to please followup and clear the issue and kindly make the arrangement of refund the extra amount which i paid from the date i submitted written request for tariff change.
Thank you.
