Outstanding tax demand

I filed form 10E and IT Return on 26-07-2017 . Due to some error in the original IT Return, I filed revised 10E and IT Return on 1-08-2017 again. E-verified both the original and the revised one. However, on the efilling portal, I saw an outstanding tax demand based on the processing of the  original IT Return.(The revised IT Return is not yet processed). Actually that outstanding tax amount is addressed properly in the revised IT Return and I am rightfully entitled for a refund. However, because of my lack of knowledge , I submitted the button DEMAND IS CORRECT and paid the outstanding dues, thinking that the same would be refunded to me when my revised return is processed. But I have come to know that once I agree to the  outstanding tax demand , the revised return is not processed. Therefore, I have to forfeit my refund claim.
What is the way out now?
