Bad product and after sales

I am very disappointed with the quality of Samsung products. I purchased a Samsung series 5 40 INCH LED TV about 3 years ago. Recently a small shadow appeared on the TV screen, I took it into the repair centre to fix and I was quoted R5500, that's R500 more than I paid for the actual TV. Believe me, I am a person who looks after and appreciates their possessions so a I am utterly disgusted that a so called high end name brand product could break after such a short time and cost more than a new one to repair. It's ridiculous. I also own a few other samsung products like a TAB S and and a digital camcorder and cell phones. My faith in this company is totally shattered and I feel that they care only about making a sale. Products should be made to last a bit longer than that ! According to the technician the Display panel needs to be replaced, it was not damaged due to negligence, it just was built inferior.They have a term for it too \wear and tear"";damn"""
