Violation of consumer rights

In June 2023, I bought a 2-in - one stroller at the shop for R3500. Myself and the shop assistant at the till went through the stroller to see if all the parts were there and whether it was working. At this specific point everything seemed well. My baby was due in September as every new parent would know planning is essential when you expect a baby. I kept the slipt and the manual instructions of the stroller. In December 2023, I noticed after taking my newborn from the stroller (which can be used as a car seat too) that the cap of the stroller is damaged. The cap is covered with maroon material so unfortunately at the time of assessing the stroller in June, it would've been impossible to pick up a crack which could possibly be hidden underneath the material. I went to the shop and asked to speak to the manager. There were two managers assisting me. I requested a refund for the stroller as I was dissatisfied with the product and the quality. I got told by the manager that they cannot refund me, as they have a 7 day policy on goods, which means if the product breaks after 7 days they cannot refund. I explained that unfortunately no good parent will buy a stroller 7 days before the arrival of a baby, and neither 7 days thereafter. They indicated that they would need to phone head office as they need to discuss the matter with them. They also took my contact details and mentioned they will phone me back. Two days thereafter I followed up, as I have not heard anything yet. I got told by the manager ont he phone that they will exchange the stroller for another one on the floor (already opened, and tested by customers). They took my maroon pram and exchanged if (without a slip) for the navy one. End of December 2023 I realised that the handle of the pram is squeaky and if was stuck. I could not be extended and therefore I had to bend over to use the stroller. I went to the shop in January and requested from the manager a cash refund as I realised this stroller is unreliable and not trusted. The manager again mentioned that their policy indicates that no cash refund can be given. She indicated that they would have to follow up with head office again as well as with the supplier. I knew at the back of my mind that the supplier is from China, and the product was imported to South Africa. Nevertheless, I demanded that I want a cash refund. The manager supp**** my husband with contact details of a contact person at head office, and she requested that the stroller should be brought back to the shop as they need to assess the problem. This morning my husband got told that the pram has been fixed and is ready for collection. This was not our request initially. We requested a refund as I knew that there is a manufactor default with these strollers. Which upset me even more was that the store are now reselling my broken maroon pram on the floor again, and this after I have been told that they will keep it in storage and sent back to head office. When I read up in the consumers act it specifies clearly what my right as a consumer is. It also stipulates that I have the right to choose whether I want a refund, replacing the good or repair the good, and that the supplier cannot choose on behalf of me. I feel that my rights as a customer was violated. No parent have R3500 lying around. Neither do I feel safe to transport my baby in a repaired stroller which may just cause serious harm to my child. Can anyone advise what I should do, as I feel this company/ shop is not attending to my right as a customer, and neither are they respecting my financial posistion or the safety of my child. I still request a refund, as I would like to buy an alternative stroller for my child.
