South Bihar Power Distribution Company [SBPDCL] — Arrears in bill even after paying it long back

Sir,
I Shailesh kumar singh, consumer ac no[protected],
legacy no[protected],
is a consumer of south bihar power distribution company ltd, my bill(bill no-no[protected]) in which arrears of previous bill for rs.1513.9 is shown, while consulting & talking about that the said amount is already paid. The receiving officer signed on the bill & said to pay the amount 1134(only for the current month) which i subsequently paid.
Again bill for the month of jan-2016(bill no-[protected]) comes in which the arrears of 1525.55 was shown. When i again consulted the concerned authority, they said as there was a problem in their kiosk, so they have not updated this & said to pay entire amount along with arrears (rs 3461), which i had not have at that time .Also in that case they do not issue bill if advance amount is shown in there system.
Therefore, i have not paid that amount, after consulting several times i was only orally assured that it will be corrected.But nothing happened.
It is company's regular practice to harass consumer, sir i am govt employee & aged also. I can not afford regular visit of office, three months ago they have provided 3 months bill altogether saying that there was a problem in their site for why they were unable to generate bill for three months.
Is this the way for business, kindly help me in this regard.

With lots of hope & regards,
shailesh kumar singh
