Regal Security (Han Strijdom) buyer be aware - returns not guaranteed on faulty purchases

for Second time now Regal has disappointed beyond reprieve, bought a HDMI splitter, some of the ports were not working and intermittently on and off or not work at all, returned it and the "technician was not available", took it back today and the technician indicates that 7 days were already past hence could not return it (already bought a replacement - they refused to change it as technician was unavailable), and apparently I should have driven all the way to Benoni/Edenvale branch (during COVID). Is this is the new normal of customer service, they refuse to offer a simple service at the right time and it is my fault that I needed to drive 30km and I was not guaranteed that technician was gonna be there, for as simple gadget that actually costs more than 100% over similar gadgets which I bought and is working perfectly?? I dont require as it never served my purpose, needed a refund, you can keep the money and the splitter goes to the dustbin. bought a Network switch last year, needed to change it but they could process a replacement due to load shedding.. my time is as important as yours and furthermore am the customer.
