Broken television screen broke my trust in Samsung repairs

Our television started getting a black screen a month after the warranty ended. I called Samsung. They tried to fix it over the phone but unfortunately the problem was not software related but hardware related. I paid the call out fee. They came and assessed the television. Gave me a quote. I made payment. They collected the television. That is where our problems started. I have had to make numerous follow ups as to how far the repairs are after being told that the parts are at the repair centre and the television needs to be collected. I have left name and number. The technician kept saying he would call but never did. Friday 23 February 2024, I call again and the technician says that the television will be finished same day and either be delivered same day or latest Saturday 24 February 2024. He assured me that he was almost done and that he would call me once he was finished and the driver would call me for delivery. Whole weekend nothing happened. I called Saturday and they informed me that technician was on leave. Same technician who on Friday said he would call me Friday or Saturday early morning. Monday 26 February 2024 I go to the repair centre in Hatfield Pretoria. Technician tells me that the television is done and it will be delivered Tuesday. I told him if it is done it will be delivered Monday. Monday afternoon I get home and the television has been delivered. Unfortunately, the problem that was supposed to be repaired looks like it has never been repaired. The WHOLE SCREEN IS BLACK. To make matters worse when you switch it on it looks like it was dropped. The television came heavily wrapped up like a mummy so it probably was not on the journey to my home that it was dropped. This matter needs to be investigated as the television screen was not dropped before going to Samsung. This should also be urgently rectified or my television replaced.
