ICICI Bank — ATM withdrawal amount cheated

Address:

Dear sir,

I have been cheated by icici bank where i have my salary account...For an atm withdrawal, where i actually dispensed only 50%of the money i asked for, whereas the 10, 000 entered on the atm machinemy account has been deducted from my account.
I have been writing and speaking to the customer care from the same day . Now it's over 35 days and they have sent me a message that they cannot do anything about it as it is a successful transaction.
I am being penalized for their fault of not having a security person or ups at the atm. I was forced into using the other atm(Kotak mahindra). Instead of checking out on the cc tv footage and giving me justice, they conveniently usurped my hard earned money.
Is there any way you could help me out or suggest that i can take legal action against them and claim compensation for torturing me for their negligence.
