Hi, it was my first year as job and while e-filing ITR for AY 2011-2012 i did mistake and filed for AY 2010-11.Then i got
reply from CPC,bangalore that no TDS was collected in my account.i realized my mistake then and filed original return for 2011-12.i got refund but CPC has deducted tax adjusted on demand as according to their records i had income in AY 2010-11(due to my wrong filing).i had even filed for rectification for 2010-11,but even that is being rejected.can you tell me how should i proceed.
