ICICI Bank
Not able to get my matured FD amount

I have opened FD AC (625314049069) with ICICI bank, Kumar park Branch, Bangalore on 27/01/07 and it got matured on 21/02/08, I have not received any Certificate till date, I have visited branch office twice, they say they don’t have any Certificate, and customer services tell it is with branch, branch manager says he will call and let me know the update, but I have not received any update. I am very upset with the banks response; please take necessary action
