Help needed to salvage plants

[iceicebaby]

Hi I bought some orchids from a local nursery.
The plants looked pretty ok except for the fact that the characteristic roots of epiphytes were missing.
This surprised me.
When I reached home I dug them up to inspect.
What I found horrified me.
Each plant was planted small container that was in turn burried in the larger pot.the pot was filled with a potting medium that looked manure.What I understand is that some novice had try to take care of the over grown (epiphytic)roots byreplanting it in a bigger pot.
The roots that were burried in this medium have started rotting and so also parts of the psudo bulb.
What I have done is I have removed the small containers with the plants and put them in the open so that they dry up and the roots get a chance to breath.
I hope u understand what I am talking about.
would like to have your view on it.
