ICICI Bank - internet money transfer to invalid account number

Hello,
I have my salary account with ICICI Bank, Indira Nagar branch, Bangalore. On 11th March 2008 i have wrongly transferred Rs5500/- to an account under UCO Bank, Indira Nagar branch, Bangalore.

Soon after the remittance, i have visited to my salary account branch and intimated this fact but i'm being told that nothing can be done as the payment already been processed to UCO Bank irrespective whether account is a valid account or not.
account number to which i remitted the money is 209010045672 which doesnot belong to UCO Bank at all.

Then i have visited uco bank too but nothing happend till date and i have not received my money yet.

Thanks
Ranjan
