Jodhpur Vidyut Vitran Nigam Limited [JDVVNL] — Not received a proper bill for (K.no[protected]

Address:

Bikaner, Rajasthan, 334001

I am having a bill for ₹400 which is incorrect its a office copy which i am having right now... The person who gives the bill told me that it is a fix charge no unit charges. You have to deposit the remaining amount of this bill and future bill of 2 months both at same time.
It will be difficult for me to pay a total amount for 4 month later because i will spend that money as of busy works. I need my bill for the last 2 months with all unit reading
