11 January 2018 I had filled IT return for AY 2017-18 in ITR-1 on line on 19.07.2017 and in section 89 ,I had filled relief after spread over the arrear amount received in FY 2016-17 ,for the due amount for fy 2016-17,2015-16,and 2014-15. I had also filled on line form 10e on 25.07.2017 and received the acknowledgement from CPC. Now CPC have sent me the mail communication without relief under 89.
In the original return filled by me I had asked for return of rs 7040 taking relief under 89. But without considering relief under 89 CPC have sent a demand for rs 16580.
Pl suggest me the next steps to be taken by me,so that I will get refund instead of demand from CPC.
