ICICI Bank — employee cheated

Address:

Faridabad, Haryana

Dear sir i got a saving account in icici bank.I deposited some cash in the icici 21c faridabad branch on 20/5/2013 details as follows-:
Account Holder name: Meenu Handa(my wife)
A/C no.[protected]
now the discrepancy is that in the deposit slip notes denomination is (100*5=500 & 500*71=31500 grand total 32000) i made this mistake where it should be (100*5=500& 500*71=35500 grand total 36000) deposit recipt with me says (100*5=500 & 500*71=31500 grand total 32000) but when i check with with bank file there is cutting done on that file instead of 71 notes there is 63 notes of rs 500 and there is sign on that cutting which is not mine but in my copy there is no cutting done means someone has done cutting intentionally on 07/06/2013 i came to know about this and after visiting in the branch they denied that there is no fault of bank/cashier as they got full trust on him & on 08/06/2013 i visit that branch again to get certified copy of that deposit slip then they told me to write a letter for this which i did and they (bank manager) will do the internal inquiry on this and check with the legal procedure that they can give the photo copy with stamp of that slip to me or not.
Please guide me about this case what all my rights what action do i take or what is the legal procedure i can do
