Bad after sales service and poor quality

I've had the worst after sales service from Samsung SA in a period of less than 3 months. First a tv I bought less than 3 years ago just stopped working, getting stuck in a bootloop, when I reported it I was told it is out of warranty and was quoted R12000 to replace an apparently faulty screen. Samsung used to have reliable products but clearly not anymore. Be ready to buy a tv every 2 years if you decide to go the Samsung route. Then I bought another tv, only for it to a have an out of box fault, with a blue vertical line striking through, instead of them getting Game to replace it, they are now taking me from pillar to post about getting the tv repaired, only because I only opened the box after 7 days of delivery. How on earth do they already book a 2 week old tv for repairs? I am certain I not looking anywhere near Samsung the next time I want to buy electronics/appliances.
