Please help, new Cymbidiella is dying

[limak]

Hi,
I received my Cymbidiella Rhodochila a week ago and it is dying. I have no idea what is wrong with it. A new flower growth and a new leave growth turned black and mushy and fell off. About 6 leaves turned brown and crispy and also fell off. There are also black spots on the leaves. I am not sure what the problem could be. I thought it was under watering because of the leaves, but the brown mushy new growth makes me question it. Finally, some of the new flower buds turned black and fell off. I am worried that if this continues the whole plant will die. Someone please give me advice. Thank you.
