Generating a wrong bill, it's very surprising that i am not using electricity from the last seven months, occasionally i come to my home town (Bihar, jhanjaharpur-godhanpur). What is the meter charges are agreed but generating the wrong bill not acceptable even nobody living at my house and electricity not consuming? Could you please take action as soon as possible.
While complaint to their site (https://nbpdcl.co.in/(S(qp4rzt0psimoe0pwdjpysqoa))/frmGrievances.aspx). its always sowing invalid ca number. But in the bill, the same ca number is mentioned and every month i am paying the bill with that ca number.
