Dissapointed

I purchased a 1/4 lamb pack from BLUFF MEAT SUPPLY CHATSWORTH DURBAN a week ago only to realise once it was cooking it was Sheep and some meat was on the braai. I called up the manager not because I wanted a refund but so he can be aware of whats going on in the store and all he said is that nothing could be done and didnt even apologize. Totally upset with they service. Please guys you need be careful with what you are purchasing
