Irate and very disappointed

Good day My name is Nakedi Usiba I had recently purchased a skirt at Burgundy Fly on this date the 09/11/2018 and received an invoice via email on this date the 12/11/2018 and upon purchase I only received a receipt as proof of purchase. I was assisted by Lerato Konyana who I presume is the store manager, I had asked her what would happen if I was not happy with the skirt if I was not happy as I needed an outfit for Thursday the 15/11/2018 for an award ceremony at work. She clearly indicated I can return the skirt however she did not tell me about the no cash back policy clause that they had as I only received the invoice on 12/11/2018. I took back the skirt on Sunday 11/11/2018 as I could not fasten the zip. I was made to fit more than 8 garments which I was not happy with and all I really wanted was my money back like any other store would gladly give back if customer is not satisfied with a product. I am currently frustrated by the level of service which I am receiving at a proudly black owned South African store who I was truly supporting and now stuck with nothing but a receipt and invoice but no product this is R1600.00 we are talking about which I cannot afford to let down the drain in these tough economic times. I sincerely hope that the Ombudsman gets to see this as I consider this to be **************** as if I was informed about the policy I would not have purchased by their store and WORSE I have been told that I will only be given a credit not in store to purchase at any given moment which I feel is a serious violation of my buying power as it seems like I am being forced to leave my money at Burgundy Fly, is this how we are being treated in 2018 where the moment you enter a store in so called Rosebank you cannot return a product you do not like where I am sorry I believe if it was a different racial group I strongly believe this would not be the case. I am considering in opening up a ******** case of ******* against them as I believe this is not fair to me the consumer.
