Newly purchased onoine Cattleya, diseased need refund or not?

[orchidhope]

Ive attached jpg photos. Purchased my first online orchid Cattleya Chief 'Sweet Orange'and researched/read all that I should do: quarantine, treat, etc. and I have come to notice the black at base of the new shoot (sarong) and then there also is a raised crusty-looking black circle with beige center on leaf - the mark does not penetrate the tissue on the underside just a bit darker from the shadow showing through. This collectively alarmed me that the Cattleya was diseased but then on the opposite of the worst of the black at the base of the new shoot (sarong), are two fresh green nubbins - roots or other? A jpg photo of that is attached as well.

Do I ask for my money back concerned this is not a healthy plant that is going to survive?

I also just noticed an old overgrown Cattleya I own with at least five new shoots/sarongs and they also have black around their bases.

I'm confused at what I am seeing here. Please educate me on whether this is normal or a fungus/disease and I should seek a refund.
