Unfair return policy

01 may 2022 My daughters father bought clothes for my daughter using a card at Africa mall and he sent them to me. Some of the clothes he bought were big and didn’t fit my daughter. I went to truworths Jabulani mall to exchange the clothes and was told I couldn’t exchange the clothes because I didn’t have the card and wasn’t the one who bought the clothes. The lady advised me to get a letter stating that he gives me permission to exchange and ID copy. He only sent me the letter on the 3rd of June 2022. Then the next day on the 4th I went back to truworths Jabulani and asked to speak to the manager whose name is Kenneth as I realised that it had passed the 30 day return policy, and only 3days had passed and the manager refused to help me and said the lady who worked there gave me the wrong procedure and he was so rude about the whole situation. I am so disgusted and really don’t understand the customer service and truworths return policy it is not fair for consumers and other stores you can return clothes without needing the letter and ID of the buyer. It is so time consuming and unfair to consumers. Let me know what must I do with the clothes as this is not my fault.
