Terrible service from Khaya at Pick n pay hyper

I am super disappointed in the service I received at pick n pay hyper Faerie Glen. The supposed manager by the name of Khaya was shouting at me when I asked to see the procedure he was telling me about that did not make sense. He even walked away to say he is not entertaining me, when Faith was trying to remedy the situation suddenly wants to try and help me. I don't know what kind of customer service was he taught but the service he gave me was terrible especially because he couldn't backup what he was talking about
