I had efiles ITR-1 first on 31st July, 2012 and again on 31st August, 2012 since I made some corrections in the IT calculations and paid some more tax in august 2012. However, some excess amount of income tax was paid due to my mistake and also due to hurry I neglected income tax deduction due to house rent. The amounts are not huge though, about Rs700 excess paid due to neglecting house rent deductions and about Rs85 paid due to a strange issue: the excel sheet showed this amount to be paid as interest but that happened since default date set in my computer was wrong (shown to be september, 2012 while in reality it was august,2012). Can I claim refund of these excess amounts paid? or is it too late to claim? In case I can, please tell me the way to do it.
Another issue is that after efiling two returns earlier, I received two statements from IT dept at bangalore but the pdf files were corrupt and I was unable to open either of these two files. What should I do about this? (I had duly sent signed ITR-V two times and I am sure they had received these).
