@TimesWastn Roses won't die as long as the roots are well packaged. Some of them are even sent bare root and at a much cheaper price. Some seasoned rose growers won't find it a problem. But some companies do send nasty or even wrong stuff. You could google
bare root roses winter care.
If you are worried, send them a worrying note and show pics to them on email which can act as a digital proof that you have raised your concern. If they don't grow or diseases can't be detected now, you will have recourse, saying that they die and you have warned them at a certain date. That's what I did with my peony. They said to me keep me for a while and see how they fare. One literally had no new shoots which should have been seen. So I sent in a sales of good act and they refunded me. I sent me pics on both occasions. One Tom Eckhart is certainly beyond hope!
Could you share with us your photos please?
Here is what I've googled for you.

23 Sep 2014 - Bare-root roses: Plant in late autumn at leaf fall, and from late winter to early spring, before growth resumes.
Avoid planting in the middle of winter when the ground is frozen. Containerised and container-grown roses: Plant all year round, provided the ground is neither frozen, nor very dry.
Grow them in a pot first or leave them in the pots they came with and only plant them out when the ground is not frozen.
