Query: The 8 oz Bottle is a completely different product in both color and odor...... Not fragrance... very unpleasant odor

This is the 8 oz bottle that is completely unsatisfactory.... It is obviously a different product than what is in the 2 oz bottle.... It is a very dark, dark Blue instead of a light blue and has an extemely unpleasent odor.... How do we go about returning it for a refund? My husband has been using Royal Copenhagen for years and this is the first and only time it has been bad.
