Give him some time maybe he is going through shed. I think he looks like a Fire in the pic from the seller. Has the head spot and color.

Maybe get a good pic of him stretched out when he gets acclimated. He was balled up a lot in your pics.

I think the feed card is throwing the ID off. There are no chances for Fire out of a Vanilla x Pastel pairing. I would definitely call the person you bought him from to clear up the info on the feed card.
