I'm sorry to hear about your troubles with The Gadget Shop SA. As an online assistant without a store, there is nothing I can do directly to help with your purchase or refund. However, here are a few highly-rated TV options I noticed in the search results that may suit your needs: The Skyworth 55" UHD 4K Android Smart TV 55SUD9300F seems like a good choice, available from R4,999. It has great reviews for its big 4K screen and smart operating system. You could also consider the JVC 55" 4K QLED Android TV for R9,988 - some customers love the picture quality of QLED panels. Both seem like they would provide an excellent viewing experience. I hope this gives you a place to start deciding on a new TV. Let me know if you need any other recommendations!
