Tamil Nadu Electricity Board (TNEB) — Bill payment

Address:	Tirunelveli, Tamil Nadu
Website:	TNEB

I have paid my TNEB bill amount of Rs.4110 on 28.9.2015 before due date ( service number..[protected] through IOB net banking.Bank transaction number.809521.But the amount has not been adjusted towards my bill till today.When i personally went to the local TNEB office today to clarify, they are asking me to pay the amount Rs.4201 with fine.They are not ready to take up the matter with their head office in this connection and don't seem to be customer friendly.I got confirmation from the bank that the amount has been credited in TNEB's account on the same day itself...ie. 28.9.2015.I am a senior citizen and very much mentally upset.As i am a pensioner, this amount is very big for me.
