Defective product sold by Makro

I went to return a defective product sold by Makro, Rocka wireless earphones (black one and white one). I actually wanted my money back but Linda Gobiley from their Returns department told me they can't give me a refund since it's past the 14 days. This info is not stipulated on the till slip I received and was just told that Rocka would need to check the earphones. I actually don't want the product, even if it gets fixed. Rocka has bad reviews and would not like to experience ANY of their products. A Nombuso Tshabalala from their Multimedia department tells me that I should have returned the product within 7 days from purchase as per the CPA. Why is this info not on the till slip? Makro continues to sell this defective product and has employees who just repeat a script and don't actually listen and empathise with customers. Rocka earphones are a piece of junk and I want my money back.
