Q.I received a Pink Double Knock Out Rose #3 size in the mail and it came with a lot of it dirt in the bag not the pot. The leaves
were starting to wilt. So I put the dirt back in the pot and gave it some water, a couple of days later I cut off all the buds and replanted it. It still looks like it is dying. Most of the leaves look dried out and wilting. There is 2 or 3 nice green small leaves. What can I do to save this plant?

It looks like the folks that sent you the rose did not pack it well, nor prep it well for shipping to you. I would let them know about that ASAP.
Your rose's soil dried out, thus likely killing some of the feeder roots on the plant. The roots that are left simply are not enough to support all of that top growth. Take off any badly wilted foliage that is starting to dry out. If the canes or stems are still nicely green, leave those canes/stems alone. If the canes/stems are turning brown to black, prune them down to good green cane material. Definitely leave all good leaves that remain. You may lose some more of them before things turn around.
Move the rosebush to a bigger pot with drainage holes in the bottom. Keep what soils are in the current pot as tightly to the root system as possible for the transplant. Once transplanted into the new pot and soils, water the rosebush well with some water that has a root stimulator product in it. The root stimulator helps the bush develop new feeder roots and gets the existing roots to growing again. Once the bush recovers well and is starting to form buds, you can plant it out in a garden or rose bed if desired.
