Lost Slip

I bought a garment on the 31st August 2019, just after 14h00. I somehow lost the slip and wanted to return the 1 item but only got a chance to go today. Normally if I don't have a slip they will look for the duplicate if u can specify the date and even better if u know the time more or less. Today, like ALL the other days Truworths Sandton City staff made me nauseous with their arrogant and very unfriendly attitude! I asked the one lady if I can maybe get a gift card or something in return of the item but she called the guy that was on the till. This is the same guy who I feel underestimated me the day I bought the items. He said if it was on acc he could help. I asked him if he can go look for the duplicate and he said no there's nothing he can do. I asked for the nr of HO and called them but the lady ****ed me off further and told me they can only help acc holders. So what about CASH CLIENTS? And what about the other times when they assist without a slip?"""

Is Truworths not guided by the CPA? Whih clearly stipulates that a customer has the right to a repair, refund or replacement?
