a return was filed wrongly on 13th may 2015. by mistake the html error message was overlooked. error code was t-fv-3141 (challan details mentioned in stmt not present in challan file imported). since the csi file was incompletely downloaded, we tried to revise the return by requesting for conso file. the site took us to 'request for online correction', where we added the challan to the statement. we submitted the correction statement, but now that is also showing as processed with defaults. please tell me why and how to proceed further, asap.
