Bad treatment

I was badly treated today by a man who works at legit Tsakane mall.I wanted an advice of what I can do since my laybye is near to expire,the cashier advice me to cancel the laybye and pick the ones I wanted most with the cash,we proceed then ,the man came and punch the items ND choose for me the ones I must take,saying he won't allow me to take all of them since they are being marked down,he further told me there's nothing I can do he owns the shop ,i ended up leaving everything,all the items I wanted he denied me buying them.I will never set my foot there ,he doesn't respect customer service law ,ND he doesn't deserve to work with people the way he attacked me for something that doesn't belong to him.
