Samsung - broken

We bought a 70” Smart 4K tv on the 25th of September 2021 and already it’s broken. Last Thursday we were watching a movie and out of nowhere the tv started clinching and then turning itself on and off. We immediately put of the plug and gave it a few minutes to “reset”. When we plugged it in again it was just doing the same. We then googled the problem and it seems that we are not the only ones experiencing this problem. We unplugged everything from the tv, disconnected the WiFi and left it over night. I logged a query with Samsung that day. The next morning we connected the power cord and plugged it in into a different wall socket, but still the same problem. I then had a live chat with someone from Samsung and they said they escalated the query and that a technician would contact me. Saturday morning a technician sent me a mail to unplug everything, give it ten minutes and then to try and switch it on at the tv. This didn’t work and I rep**** that we tried and it didn’t work, but there was no response Back from the technician. Monday morning Samsung contacted me again saying a technician will contact me to come inspect the tv and this might take 3 to 5 days. It’s Tuesday and my first logged query was Thursday. Our tv is still broken and trying to let my 2 and 3 year olds watch movies from a laptop without pressing anything seems impossible. How can you expect a well established company like Samsung to tell you to wait 3 to 5 days for service? Is there so many products giving problems that a technician needs that much time to fit in an assessment of a tv? When we bought this tv I choose Samsung because it’s a well established brand, but now I am regretting my choice. Seeing all the same problems with TVs are also a big discouragement and I will not ever suggest Samsung to anyone again.
