No refund provided id document

I just been to the Exact Store in Century City Cape Town.I have been given a run around by the store agents who first took long to assist me. I have cancelled my laybye due to the fact i no longer need the clothes as i opened new account. Spoke to Lee who firstly advised me that they will take 1percent of the amount i paid i was totally fine with it. Know came Yandiswa who is appearently the stock control who has a attitude said whispered to her saying laybyes cant be refunded i kept like i didnt hear,So she came to me and said i must produce a slip even if its a statement then i said will go print statement on my email she then changed and said that wont make a difference they need the real copy as they need to see how much i paid so they cant refund me the money will be credit noted i dont want credit note i want that money Yadiswa said i must see what i must to do as this law has been like this im so disgusted with her attitude and the reaction she gave me as if im stupid if this how you treat your customers she can have that money as tip as her attitude sucks.
