I have Customer Service training as part of the volunteer orientation.  You can view this information in my Volunteer Handbook which is on my website.  Go to http://www.saintjosephhealthsystem.org/volunteer.  Once there, click on "Orientation" in the left hand column.  The handbook is the first link on that page.

I also added a permanent column to my volunteer newsletter dedicated to Customer Service.

I went to a conference a few years back where I heard Margie Harris speak about staff training.  I purchased her template and create my own staff training manual.  I then meet with every department that accepted volunteers and sat with them to go through the manual.  You can get this template at http://www.higherimpact.net/integrating_staff_and_volunteers.html

I chose not to have live training sessions, which Margie recommended...and really it would work better if we did it live but we simply do not have the staff or the time to do this.
