Niantic Ban refund?

Hello, Apple seems to be helping Niantic rob me.

I purchased some pokecoins from Niantic in the Pokemon Go app as an in-app purchase. Then months later they banned my account. I asked if they would transfer my purchased coins to a new account they said no. So they take my money, deny me access to my purchase and then Apple are facilitating the theft because it's been more than 90 days. Niantic should not be allowed to rob people like this. I will not buy anymore in-app purchases through Apple I have learned my lesson.
