Flat beers

Have been supporting this company for many years spend about R1500 per month on beer. Recently went camping with two cases of beer and every one was flat. Had to just drink it ss we were camping remotely. Bought a case of beer and one of the bottles had a broken bottom and was empty. I am very disaapointed with SABS as I asked at the bottle store and we are not the only ones that have complained that beers bought were flat
