Open letter to Income Tax Department

Open letter to Income Tax Department (posting a mail for which I did not receive any response from them)

I have THREE different issues to report here.

1. For my PAN, my latest IT Efiling was done from a Bangalore based address.
   But the IT efiling website still shows my old Chennai based address.
   How do I make sure that the latest address gets updated for my PAN ?.

2. With respect to latest Communication Reference No : CPC/<>, dated 19th Oct 2011,
    I have been asked to pay Arrears for the following years.

a)  Year   2005 :  Rs 240 as Arrear.
     Only few weeks back, I got a refund notice of Rs 240 for the same year.
     My latest Form26-AS for the current year shows the same.
     May I know  Why the refund was done followed by a Arrear demand for the same ?.

b)  Year 2007 : Rs. 2311 as Arrear.
     Year 2008 : Rs 4650 as Arrear.
     I have paid the Self-assesment tax for AY 2007 & 2008.
     Form26-AS for AY 2008-09 has the details for the same.
     I am wondering why these arrears are being demanded now.
                   
3. As per the latest Communication Reference No :<>,
    dated 19th Oct 2011,
    I have been asked to meet the current AO. Since the IT Efiling website doesn't have my
    bangalore based address, I am not able to find the right AO in Bangalore.
   When I call CPC Customer care, they are asking me to contact AO in Chennai who made
    the arrear demand. Can you please help to find the correct AO for communication.

Thank you.
