Well, This is for PVVNL (Paschimanchal Vidyut Vitran Nigam Ltd., Meerut) Users only.
It is a big challenge for us to find the old payment and billing details in ledger. Online system is having details since 2017 only.
We need to check it from ledger manually for Bill revision.
Now, our task will be easy as SAI Computers have developed a portal to find the old ledger details.
