Samsung tv

TV started flickering going on and off eventually it went on and started creating lines on the TV, called the call center in September 2022 nor ticket or query was even logged,eventually the lines went away now it seems to be doing the same thing on the 1st Nov, I need my TV repaired it is still under warranty, if this is the service from Samsung I don't advise others to pay so much for low quality brand I prefer to stick with hisense my TV I had for 5 years no issues sold it in good quality also .
