I will Never Buy at Decofun SA (Furniture) Anymore

My name is Lindi and I work as a Business Development / Key accounts Manager. On Saturday 15 September I went to Decofurn Boksburg to show my 26 year old son some furniture there since he bought a new townhouse in Boksburg. I then decided to buy a Queen size duvet inner. The followingTuesday I removed it from the plastic and I noticed that it had uncomfortable bumps. I felt it and did not feel comfortable with it. I put it in my duvet cover and it look funny since it was not smooth but very bumpy. Since I was working on Wednesday and Thursdays I was only able to return it this morning. On arrival at Decofurn Boksburg. I was told by cashier to go show it to the warehouse manager at the back of the store. His name is Jacques and upon inspection of the duvet inner that was in its original pack he said I can get my refund. He told me that they have returned bedding before as long as it is within 7 x days with a receipt and original pack. I told him that since I regularly buy at Decofurn I dont want to wait 7 x days for refund, I would rather take 1 x black barstool and pay the R300 difference since their Duvets inner are not comfortable. Jacques said that is perfect. Another lady came by the name of Alta and she said I cant exchange or refund duvet covers. She was extremely rude and she walked out and went to the STORE MANAGER. His name is also Jacques. They spoke in Afrikaans explaining that I cant get an exchange or refund. I took my phone and tried to call the customer service manager at Decofurn Head Office. While jolding on the line for Head Office I was approached by the STORE MANAGER Jacques and he refused to exchange or refund. I was very upset as the first Jacques said everything is fine. I left the shop and tried calling their head office without any help. Johan at their Head Office phoned Jacques and when I called him he did not listen to me bur gave me the same response that Jacques told me. He confirmed to me that he spoke to Jacques (Store Manager) first before calling meThe duvet was R329 and I left it in the shop. Can you please assist me to get my refund since it was less than 7 days and I had my receipt
