India is on the list of visa countries, and isn't on the list of visa on arrival ones. This means you have to have one, whether an eVisa or a sticker. Having a Schengen visa makes you eligible for an eVisa but doesn't exempt you from needing one.
It is possible to appeal the decision, note however this could take longer than your ban period, depending on procedure.
