WRONG ORDER

A one star for the treatment I got today. Been buying meat here but I have not encountered any problems before. So we went to buy meat the previous Saturday and one of the products we bought was pork chops. The item was labeled as pork chops outside but turned out to be beef inside. I only realized that upon cooking. Please do take note that I do not know anything about meat, you can literally place different kinds of meat on the table and I would not be able to tell which is which. I called them and explained the situation and was given a number I should text. On the text I indicated that I only realized upon cooking that the meat was not pork and they said that I could return the product and they will exchange. So today my husband went to change the meat and was spoken to in a dismissive manner, being told that they do not take items that are opened, understandably so but whose fault was it in the first place that we did not get what we ordered?and how on earth was I supposed to know what kind of meat am I cooking when I do not know anything about meat?...I really love this butcher but the way they treat their customers??? So we were basically supposed to see it upon ourselves what we do with the meat even though it was not our fault?
