Samsung Smart TV problem

I recently bought a Samsung Smart TV. I paid R450 for the installation, and mounting onto the wall bracket that my previous Samsung had been on. There was a media player attached to my old TV, so the installer just put it onto the new one. I immediately had problems with the TV switching itself off/on at random times. It sometimes happened 8 to 10 times in 5 minutes. I contacted Makro, who ignored my complaint. I went online and saw that this was a recurring problem with some of the Samsung Smart TV’s. One of the things that was suggested was that you have no attachments, like media players. I called the installer back, and had it re-installed without the media player – another R350. The problem did not resolve, and I called Samsung for remote support. The technician was able to connect to my TV, but he said that the screen came up blank, so even though we went through the process of re-setting the TV, the problem persisted. I called for remote support again, but was told that I had to take the TV to Samsung for repair. As I’m in my seventies, and unwell, it would cost me another R350 to get someone to take the TV off the wall for me, and another R350 to put it back after I brought it home. I felt that Samsung should send someone to check whether my settings were incorrect, and the cost should not be mine when the TV is so new. Last week I received a call from a company who said that they’d collect the TV but that there’d be a charge for fetching and returning it. As a widow of 20 years, who’s battling financially, I feel that it’s very unfair of Samsung to expect me to bear all of these extra costs when it’s their TV that is faulty.
