Lush rosebank management needs to investigate Sam's behavior

I went into the Rosebank store to exchange a perfume I bought it was new. The manager Sam was soo soo rude she screamed at me and I asked to speak to customer service she went outside and spoke to someone and refused to allow me to speak to the person. When she was so rude I said I would record her behavior she said I don't have her permission to do so. After speaking to her manager she did the exchange and a refund she said she processed however no refund has been processed and it's Thursday and I went in on Sunday. I'm not dealing with this person whose behavior is soo soo bad. I do need my refund as it was R1000 but I think management needs to look into this and refund my money. It's too far to go back and she was adamant my refund was processed. I'm never ever going back to this store but I also don't want to be ****** I need my money back. I used to support this store before never again never.
