To mitigate problem in future we wrote a letter to jsw to note the change and to authenticate the change we requested the branch manager mrs s. K. Janaki to attest the same. We were told that we would be charged rs 100/-
What we want to know why the customer should be charged for changes made by the bank which is no fault of the customer seeking to rectify the amendment?
