confirmed the stock but after paying the stock is

I'm not happy with what happened at Richards Bay branch Boardwalk Mall, I bought a fridge, I asked before buying whether its in the store, the sales man went to check it then confirmed_ all was fine went to pay cash. Then now I called in my delivery whom I paid him to take my things to home. Then the dispatch Manager tells me that the fridge has a fault and he will deliver it on thursday to me. I asked him why didn't you guys inform me before that there's no fridge in good condition, he couldn't explain _ now I luz da money I paid 4rm my private delivery bcuz of the dispatch Manager's incompetence. I'm not happy with the service I got and I discard my future wth this company
