How to appeal in against 80G cancelation order

Sir /Madam,

Our 80G renewal for the application of form 10AB rejected and cancelled by Commissioner of income Tax due to wrong selection of section 13-Clause (ii) of first proviso to sub-section (5) of section 80G instead of 13-Clause (iii) of first proviso to sub-section (5) of section 80G.

Now, how can we appeal to income tax and how get 80G registration certificate. Still the appeal login disabled in Income Tax side after issuing the rejection order in past 13 days and which section we select DIN & Notice No issued by Income tax.

Thanks

Satheesh
