Hisense TV fault in 8 months

I bought a Hisense UHD 58inch TV last year in July 2025 from Incredible Connection on special. In March I started noticing a dark "smudge" in bottom left hand corner. I contacted Hisense Durban and they sent Technician to investigate and repair... No repair was done and they told me IC would contact me about a refund. Hisense never contacted IC and had to go to the store myself to log call. They want to credit me but same TV is almost R2500 more expensive than what i paid. What is the point of a 4 year warranty when they their faulty product (panel require replacement) can't last a year and you get last years money? This is not an acceptable resolution. If I cannot get a replacement, then I will be taking my money to another brand that stands by their products.

Disappointed to say the least.
