Submit response to wrong Tax demand

Thanks Eswar Sir , I'm trying to do the same but it's asking me to pay . Please advise , what to do in such case ?

I have paid in time, I have the challan details , just the portal is malfunctioning and troubling taxpayers .

Thanks Deven sir , I just did the same yesterday but surprisingly the system generated someCRN and asking me to pay . Please advise , what to do in such case ?

Yes, that's true ,  I'm entering the same amount as demand tax amount but it's keeps on adding some new new figure in pay tax area and taking me to payment options . Please advise how to proceed further ?

If allowed here , I can attach a screenshot with the payable amount and next confusing screens tomorrow. 

Many Thanks for the timely support , Really appreciate this forum for being generously helpful on various scenarios . 

finally I could resolve it myself by following way

Disagree with Demand ( full or partial ) - > Selected 2 reasons 

i) demand already paid with open challan CIN ( entered challan details and in the top , put exact challan amount )

ii) others - entered interest amount and in the remark ( justification : already the tax has been paid well on time , hence interest charge is incorrect )

The amount payable becomes 0 and submit 

Hope this helps some people who face  this confusing scenario .

Best Regards
