Really disappointed in my latest oncidium purchase

[UsagiGreenPaw]

I just recieved this Oncidium Rex's Luck Firefly from secretgardenrareplants and I'm unhappy the plant has so few healthy roots and bulbs that are paper thin.
I'm new to growing orchids, so I'm not sure if this is standard for what you get in the mail. I have had healthier plants mailed to me. Would you ask for a refund and send the plant back?

I'm still working through the mostly dead roots, even ripped off an old tiny hollow bulb, but there still quite a few roots to go through. I pull off the thin coating if it slips off and then snip it off. If I were to keep it, would this plant benefit from being planted in sphagnum moss? There are a few ok roots coming off the newest growth.

Sigh. I'm so bummed. I wanted to get this one from Trader Joe's, but the last one in this color had some bulb weirdness I didn't know the cause of so took a chance and ordered this one. It was supposed to be a reward for a bunch of work I did last week.
