Extremely poor Customer Service - Brooks SA

Extremely poor Customer Service. I bought a value pack of Brooks Hard Seltzer at SuperSpar Vineyard over Easter. Upon opening the case a few week-ends ago, 3 out of the 12 cans were completely empty although perfectly sealed. Neither Brooks nor SuperSpar Vineyard reacted to any of the contacts I made on their respective websites. So much for a new product trying to establish itself on the South African market place.
