Samsung poor tv quality

I have purchased a 70 inch Samsung tv from game on 3rd January 2026, initially I had an issue while watching live tv only whereby the top left corner of the screen has a little blue dot, I complained and technicians were sent through, after investigating the matter the conclusion was that there is nothing wrong with the tv and it is a dstv issue while streaming live, to date i have no solution and dstv tells me it's the tv while samsung tells me it's dstv, bear in mind I have 2 other branded tvs of which I dont have this issue, now im stuck with a tv that has this issue, fast forward to 9 June 2026, I switch the tv on and now the tv comes on but there is no picture, apps and all functions are not working, I spoke to a consultant from Samsung and Nonhalanhla who is the consultant took me through some trouble shooting which did not work, I now have to wait 3 to 5 days for a technician to come through and resolve a second issue in 5 months, honestly I would advise any client to stay away from.this brand because the brand to me is poor, the after sales warranty people take too long to resolve issues and you have to run around, I am extremely disappointed and I would rather return this product and get my money back. Unfortunately I am now stuck with this tv that I am not happy with, Game says 7 day return, I was complaining from the second day and this is poor business ethics., I asked the consultant for a reference number and I was told to use my cell number, never heard of something like this before.
