Hi mytake (as in your viewpoint, or a type of mushroom?) lol
I hope you are feeling much better now and continue to have a refuah shelayma.
Your post would be valuable feedback to the organization.
I think you should let them know. It should not be a matter of any warm body who volunteers automatically has the job.
The volunteers should be screened and receive some sort of orientation, or even a completion of a few hours of a class with certificate only for the fact of impressing upon the volunteers they are not doing a quick, bing, bang, boom thing.
It is very important the volunteers have the right approach while doing this mitzva.
Again, feel better!
