ICICI, ATM
Lost money when using ICICI ATM

I lost 5000/- using ICICI atm in Oreintal Bank of Commerce

On 23-Dec I did 5 transactions using my ATM

1. OREINTAL BANK OF COMMERCE tried to withdraw 15000/- transaction failed because of greater amount requested

2. OREINTAL BANK OF COMMERCE Withdrawn 10000/- transaction successful, my balance was 17982/-

3. OREINTAL BANK OF COMMERCE tried to withdraw 5000/- transaction failed and, displayed transaction timeout message in the window.

4. Panjab National Bank, withdraw 5000/- transaction successful, But my balance was shown 7982/-

5. OREINTAL BANK OF COMMERCE Checked my balance, it was same 7982/-

Please let me know what I should do to get my 5000 /- adjusted to my account. I have already communicated to ICICI via mail, and after 15 days I have recieved a mail that they cannot do any thing as the money is taken from OBC.

Please help me how to go ahead to get back my money
