Hisense service is disgraceful!

If I could give a -5 star rating I would, I bought a 55 Q8600 one of Hisense top of the range TV’s just over a year ago from Makro, Makro made arrangements with Hisense to collect the TV which they did. The screen has a pixelation problem. Hisense kept the tv for over two weeks, with no feedback or communication. I eventually got in my car drove to Hisense (because getting hold of anyone who knows what the hell is going on is another frustration all on it’s own) only to be told they can’t do anything about the problem but they did replace some panel which I never even knew had a problem but it didn’t fix the actual problem the tv went in for in the first place so it was a waste of time. I took my tv out of there so fast and before they can do anything else to it that doesn’t need doing. Needless to say my tv obviously wasn’t fixed and with no solution being offered either. I’m appalled by the service and why bother giving a 4 year warranty when you don’t deliver what’s promised! We have supported the brand for many years but will no longer do so with service like this it’s is a disgrace!
