I went through this, too, last month! Here's my post...
Orchids arrived cold & looking sick
The original two Catts lost all its leaves.
However, when I emailed the pics of the plants' condition to the grower, he gave immediate attention and shipped out replacements. They arrived in good condition and the spikes bloomed.
I kept the two original...in the hopes they will have new growths this spring.
I hope yours make a comeback.
