Caladium bicolor 'white wing'

I pre-ordered four plants, including a Caladium bicolor ‘White Wing,’ online and picked them up 2.5 weeks ago at a pop-up show near me. The Caladium was quite small, it had three leaves—one was already completely yellow and became dry and crunchy very quickly—and skinny stems that could not support the leaves. I have it in a small room with a humidifier running 24/7, and it now only has one leaf left which looks worse than it did when I got it. I think there’s a good chance the plant will not survive.
