Sorry that you're having issues. As others mentioned, are you aware of any other shops you could take it to? It sounds like this place isn't all that familiar with tuning coilovers. The excess "bounciness" does potentially sound like a preload problem. How handy are you? Adjusting preload and raising/lowering the car is something you can likely do yourself if you have tools, a jack, and some mechanical inclination.
I am curious though...what made you go with these coilovers? I mean, don't get me wrong, these are quality coils, but if all you wanted was a very mild drop and a comfortable ride, a set of Eibach springs could have gotten that done for about $300 versus the $2K that the Fortune Autos cost.
