Manish, I have applied for refund this year AY – 2013-14 and I got an email stating: Subject: Intimation under section 245 of Income Tax Act, 1961. And said that The Refund determined during processing is being adjusted against the outstanding demands for AY 2008-2009.
The letter also says that I should respond to AO within 30 days.

I have checked my records and for AY 2008, the taxes has been paid as per Form 16 & IT acknowledgement form and no dues were pending. Can I file RTI to get this rectified? If yes, to whom I should address this to? On whose name the IPO should be raised?

I am unable to find the exact address for Range 12 Hyderabad on the income tax site. Where can I find this information?
What all information can I ask in this application?

Please add/suggest what else I can do in this case?
