Income tax refund issue

Hi,

My name is uday. I have filed my ITR for Assessment year 2008-2009 but I havent recieved my refund yet. I lost my ITR acknowledgement receipt. How can I check my refund status? I called Income tax customer care and they said they have only details of ITRs filed after 2010 and asked to contact the branch office. How can I check the status of my Income tax returns refund for 2008-2009 and also will I get the refund?

Is there a way to check the status of the refund and also whom should I contact?

Thanks in advance.

Cheers

Uday
