Struben's Valley staff don't know the CPA rules on returns for defective merchandise.

I bought a CampMaster One Touch Gazebo from Makro Struben's Valley on 5 Aug 2019 for R899. I tried setting it up on 28 Sept 2019, but shortly realised that there were some parts missing. I went to Makro on 1 October 2019 and tried to get the store to refund me or issue a credit note. They refused to do so saying that it was more than 14 days since I bought the product. But the product is defective and I think the CPA states that the buyer has the right to ask for a refund within 6 months. The staff then booked the item in (after consulting with supervisor and manager) for repairs even though this is not what I requested. I'm really disappointed in the way I was treated. They have lost a loyal customer.
