Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Chevrolet. Normally, any concerns
with the sales transaction or the
operation of the Chevrolet chassis,
or upfitted rear body will be resolved
by your dealer's sales or service
departments. Sometimes, however,
despite the best intentions of all
concerned, misunderstandings can
occur. If your concern has not been
resolved to your satisfaction, the
following steps should be taken:
STEP ONE : Discuss your concern
with a member of dealership
management. Normally, concerns
can be quickly resolved at that level.
If the matter has already been
reviewed with the sales, service,
or parts manager, contact the owner
of your dealership or the general
manager.
