Suffering Bellina

[Jenn4a]

No surprises here, I got a phal bellina off eBay, but I had them hold the plant for warmer shipping. Last Wednesday, it was around 47°F, so they shipped 2-day priority USPS. Basically the plant was in transit from 2/09-2/13.
The thing is, since he came late, he arrived in 20°F no heat pack.

Anyways, I think saving this plant (if it's even possible) will be difficult. The leaves are all wrinkled, dark green, limp, and almost mushy feeling. The roots are shriveled, but not surprising...

I know this is probably a problem with USPS, and not so much the seller. What would you do in this situation?
