Punjab National Bank [PNB] — wrong timing of bank workers

Today i went to punjab national bank, baroda, gohana, sonipat at 3.55pm
But the bank workers has closed the bank before the bank work timing
When i asked them for the reason of close the bank before time
They refuse me to tell the reason
And also do misbehave with me and said me to go away from there
So i want a strick step against these bank workers so that they work full time
Because goverment pay these workers for full time not for rest
By this misbehavior of bank workers, all villager are facing problem in their bank work
All villager want to get rid of this problem but in my village there is no more educated person
So i kindly request you to solve this problem and take a strict decision for this kind of workers so that every government worker become serious in their duty
