Poor customer service indeed

What a horrible experience at Woolworths Ballito by SIMA. I was gifted an outfit, less than a month ago for my birthday. When attempting to return the item for a different size I was told that the item holds no value, it is 1 cent on the system. According to SIMA this was a sale item and the last to return the item was the first week of September 2022. As a recipient of a gift, how am I supposed to know this. Woolworths , your customer service standards are appalling, surely this goes against the CPA Act.
