State Bank Of India [SBI] — illegal charging for a government issued cheque of my retirement benefits

On my retirement i deposited two cheques of my retirement benefits as under
05/06/2018 for rs 4913554
07/08/2018 for rs 11167370 in sbi saraswati vihar delhi both of which were govt cheques issued by delhi govt as my hard earned money of my retirement benefits
They were returned by them as they need to have two signatures in place of one and both belonged to sbi

The bank charged me rs 295 each time for this mistake of govt and none of my fault
When i approached the bank the bank authorities did not care to hear my plea and even rebuked as they said this will be charge as per bank procedure and can not be waived

I am premium customer of the bank and if the cheque did not bear the requisite signatures why did the bank sent them for clearing and the cheques were not returned because of any of my fault or the insufficient funds

No other bank is charging like this without caring for the reason of return

The authorities are requested to kindly look into matter andrefund my 590 rupees and also punish the guilty so that other customers of the bank are not harassed like this
