Mis selling

I bought two Samsung 32 inch smart tv's in July 2022 at Game Garden Route Mall George. The sales person was very helpful and when we asked him what we can do if there is something wrong with the tv he told us to bring it back that they can swop it. With that in mind we bought the two tv's. Yesterday when we wanted to switch on the one, it did not want to work. I decided to return the tv as the sales person told us. At Customer service/Refunds dept we were informed that the tv will not be replaced but send away for repairs. Very unhappy, we told the manager on duty, Heinrich, we only had the tv for 5 months but he still refused to replace or refund it. I called in to the call centre who advised the same. I checked terms and conditions on the website and decided to take the tv in for repairs. Just to hit another brick wall. I was advised bring back the tv on 10 January 2023 as the company doing the repairs is closed. Although the terms and conditions clearly say that you can be refunded if the tv is not repaired within 21 days they still do not want to refund me. We will now only get the tv back (hopefully) end of January! If this was disclosed to us when we bought the TVs we would not have bought it at Game. We do not want a repaired TV. We bought a new TV and want a NEW TV back.
