It sounds more like they forgot to fill the shock back up with oil. Gas charge has little to do with damping, and even a blown bladder wouldn't have the effect that you are describing. I would absolutely demand ALL of my money back from the alleged "shop", and send my shock to somebody else. Don't ever go to them again. Better yet, just service it yourself - it's really easy.
I had my XR4's shock screwed up by a fly-by-night shop myself. I sent it out in good shape, but it was leaking when it came back. I sent it out again, and it seemed OK after round two, but literally exploded all over my garage floor some time later while just sitting on a stand. Turns out the seal head was installed incorrectly. I was pissed. I ended up just re-doing it myself and re-valved it while I was in there. Don't be afraid - it's way easier than a fork.

Again, check out the FSM for what you need to work on the shock. I bought a nitrogen bottle and a no loss gauge/filler set (reasonably priced on ebay) some 20 years ago, have filled quite a few shocks and haven't run out of nitrogen yet...been a good investment.
