I am quite sure that there are better fits than Excel or Survey systems for such a ticket system approach. It might be possible to do this with Limesurvey, but you probably will have to do a lot of hacks and work arounds and you will only use a very limited feature set of LS anyway.
I am quite sure that there are open source ticketing systems out there that will be a far better match to what you want to do. AND: sometimes it makes sense to adapt the process to the system, rather than trying to fit a system to an old and outdated process (using Excel sheets!!!).
You might have looked into those already, but here a few links:

As much as I like Limesurvey and as much as I want the user base to grow, I am also convinced that there are better fits for your case out there.
You can't access previous responses out of the box. In surveys usually each answer is treated seperately. There are some work arounds that can be found on the forum, if I recall right, but it will always be some kind of patchwork and not ideal. You might be able to "hack" this with a plugin, but I have no experience with this what so ever. Maybe someone else can skip in there. But if you haven't done so, I would rather look into real ticketing systems than hacking a survey system for this.
