Not worth buying

I bought a 50inch Skyworth 4k tv. Not even 2 years and it started showing lines on the screen. I took it in to PNP (26 June) where i bought it. It is now 24 July and it still hasn't been collected at the store to be repaired. The only reason you get a 3 year warranty is because they know they don't care about the customers once they sold the TV's.
