Samsung smart 60inch TV

Very unsatisfied service from MHC World. Bought a Samsung 60" inch smart tv from them October 2023, April 2024 it had to be taken in for back light to be replaced. Got the TV back and 9th of November 2024 it would not switch on, took it back to same place that repaired TV in April(referral from MHC World), just to find out TV is not under warranty anymore, and received a quote to pay R8150 to repair the TV. This is truly not a joke, a year ago I paid R10k for a brand new TV and a year later I need to pay almost the same amount to repair the TV. I request MHC World to collect this TV and replace with new TV or refund of my money. I have never had such bad issues with Samsung TV in my life.
