Dear sir,
 
 
Return filed in ITR -4 online for A.Y. 2009-10 u/s 44AF. I hv filed details of Gross receipt , Exp and profit in item 45 of PART PL sheet like Gross Receipts ... Rs.669500, Exp...490490 and Profit Rs. 179010.In BP sheet same profit shown in item 33 ( iii) i.e. profit u/s 44AF. accordingly Income become Rs. 179010 and tax etc computed.
Now I received intimation from CPC, Bangalore showing income double i.e. 358020 and raised demand.
As I come to know in this forum also that CPC Bangalore is sending wrong intimation to tax payers.
 
Kindly guide course of action :

1. Should I write a letter to CPC , Bangalore by stating facts and request for rectification u/s 154 or simple letter to be written to them ? Whether letter should send by ordinary mail or speed post?
2. Should I contact to Jurisdictional A.O.at home place  to rectify the same ?
Tks
