Repotting cut orchids

[NWOrchid]

Hi peeps

Sorry to be that annoying new person of the day, but where better to find advice than from a forum of people with more experience than me...

I ordered some Cymbidium Orchids for my partner today, and thought they were potted, but cut ones arrived. I need to find out if this was my mistake or theirs.

Anyway, am more into Cacti myself, but I know all plants are so different, so my knowledge may be usless here. I was just wondering if we could possibly pot the cut orchids to allow them to take root, or are they now just in the slow waiting room for death?

Hope someone can help. Thanks in advance!
