Jewelry Return Policy Never Explained by 2 employees

On 26 August I went to Truworths Eastrand Mall to buy necklace and earrings for my cousin sister. I was assisted by the Store Manager because it was busy. Cousin sister came an Sunday and just looked at the earrings and she said that her ears are too hanging and she doesn't wear hanging earrings like the ones i bought. She didn't not even try them on. On 30 August 2023 I took the earrings back to Truworths to exchange for another necklace and I was told that earrings cannot be returned, while I went on your website and it only stated that jewelry can be returned within 14 days. There was no specifications about the kind of jewelry. Then I asked this lady to call the Manager to explain to me why he didn't tell me that the earrings cannot be returned before I bought them. He said that it is on the back of the receipt. How was i going to know that because the cashier didn't tell t to read the jewelry return policy at the back before I signed the receipt. Which means that, even if I was still in the shop and saw something else they were not going exchange them and he said yes . I find this very unfair that I will be paying for 6 months for something I'm not going to use, while the Manager and the cashier didn't give me this information. I will be happy if these earrings can be Exchanged for a chain or bracelet.
