Samsung South Africa Incompetence

Samsung's incompetence to resolve Software issue and their accredited repair centre. Having issues with OS upgrade, spend hours on phone to call centre trying to fix problem but with no success. Update shows on software update menu, starts uploading but does not install. Reset TV to factory defaults, unplugged unit, reset hub but software will not install. Eventually the call centre sent one of their accredited repair centres out, SSS Cellular AfrexportCC. The technician was not competent in resolving the issue, he thought by resetting TV back to factory defaults will resolve it, told him that we have done it but still he wanted to reset and he did, same problem software update available but not installing. he then said that they have 7 days for the repair/ solution and that they knock off at 5PM and that he needs to go and will get back to me Wednesday 4 March 2026, unacceptable! I trusted Samsung in purchasing the product that is still under warranty, but there is definitely a bridge of trust at this stage. Me as customer must wait for their *********** service centre for days to get an answer, not knowing that they can resolve the problem, my TV has slowed down dramatically as I think the update *******ed the existing software
