Bad attitude from the Owner

I called to order food (Hilcrest branch, of which I'm a regular, friends with the staff and even the drivers). The person who picked up was the Owner, Riaan. I struggled with the name of what I wanted to order (Foccacia) and I told him so. So I described it and where it was on the menu. He gave me two options for what I wanted and I asked for the latter. Upon deliver what was delivered was incorrect. I didn't have time or energy for an exchange but I still called to let them know what happened. I have never encountered such a rudeness and arrogance in my life. He said that he does this on a daily and checks all his orders and insisted that I asked for what I ordered. I said that we are human mistakes happen. He said he would know he is the owner and he maintained he didn't make a mistake. I told him all wanted was an apology. So he said, sarcastically, I'm sorry ma'am that I repeated your order and you confirmed it. I really just couldn't believe it. I told him his attitude was appealing and that what he had just said was extremely rude. He went on to say that he could equally accuse me of having a hearing problem. His conclusion that we agree to disagree and he refused any blame whatsoever for his mistake cause apparently he is incapable of making mistakes. I was really a big customer there but I will never go back. I can accept human error but to be spoken to so rudely. Wow
