Hostile manager

My friend and I went to D'aria wine farm this afternoon 22 October to celebrate a friends birthday. We did our research prior to going to the farm, because our interest was to have small picnic and also do the wine tasting offered at the farm. We called in the morning to verify if we are able to bring in our own food as we understand that the farm had a restaurant facility. The receptionist confirmed that we may indeed come with our own food as the place allows picnics for the public/visitors. Upon arrival with our basket and food at around 13H30-14H00 we went to the restaurant again and asked for approval to set-up and have our picnic. The lady approved and told us to set-up where we feel comfortable. As we got to the grass area to set-up the "manager" came and started and shouted at us and told us to leave his property or else he will call the police. He was very violent and hostile, made some horrible remarks and reused to engage us. It was publicly humiliating as we tried to explain that we had prior asked and we were not there to invade. The managers attitude was horrible and we wish to have this matter investigated . My contact details are ********** 197- **********
