Bad product

In December 2018 I purchased a headboard from @ home. I used my account to purchase there but I didn't receive it to pay r2500 into the account. The headboard was received in January of this year once it was erected I found that the stitching of material is damaged, it is obvious that this is a manufacturing mistake however when I complain to @home in January they said they will look for me for a new headboared Taking Back a few weeks later telling me that they're busy with their stock taking so they are unable to process my request now however they came back in March telling me that they are unable to find a headboard so I requested them to to provide me with a discount since I cannot accept a damaged product and I can actually use the head bolts in my spare bedroom after receiving no feedback I Made contact with them where I was in for a day will not provide me what a discount I have to pay still full amount so I requested a refund. With this I also indicatedthey will have to refund me the cash payment that I made on my account and I also be returning the headboared but now they are telling me that they are not willing to refund me the 2500 I paid on the account as it was paid on the account however they including the fact that the account had a zero balance upon the purchase of the product. I have not purchased anything additional afterwards. I have also asked them when I return the headboard I will be closing my account and will they be refunding me my money then they have still not answered this question. It is now two days later.

During one of my discussions with him I told him that this was not according to the treating customer fairly act, nor Consumer Protection Act, all National Credit Act
