Spar Tops Hoedspruit selling rotten beer

I bought a case of carling black label beer on monday the 28th of September 2020, at Hoedspruit Spar liquor store. I couldn't believe but most of those beer had already gone going bad, the taste was horrible. why are they selling us beer that's way past it's shelf life??. I was avoiding buying at tarvens for the exact same reason but it turns out even big stores are doing it. I am outraged, this is like throwing away money, funny enough this is not the first time this is happening and im sick of it, if spar doesn't want to sell us fresh beer they should say, so we can go ro other liquor stores. Right now i kind of want my money back, once it rots it's not beer anymore. Spar fix this, throw away your old beers, i want my money's worth. I trusted your shops up until now, because these's no way tou didn't know, everyone is just a ***** now, no more honest business.
