Poor customer service

I bought a beef pie and it was marked beef and I drove over 5 KM home, when I got home I opened the pie and it was pork inside. I drove back to the store and instead of getting an apology from the person who labelled the pie, he gave me attitude and said that the cashier must apologise on his behalf. I left the pie for him to eat it because I don’t eat pork and I wasn’t gonna eat anything that was made by him.
