Jvc suck big time with inferior products.

I bought a 70 inch JVC tv. I it's android based, the same I had on my55 inch tv before. 1st the color was bad, sent it back to the supplier and they changed the motherboard, but did not do anything about the other problem I reported. The other problems is when I share videos from my pc, it freezes every now and then. I did the same thing with my 55 ich tv and it worked fine. Now JVC says that rhe freezing is not their problem as it's 3rd party software causing the problem. I tried every other media player on the web, same thing. I also did this in the past with my media players. All worked fine. Had a call from Kaylen from powercare who support these devices. Every timeI explain to her that the hardware is inferior the more she carries on about 3rd party software. She has no knowledge of the product as she needs to phone JVC evevery timerytime she can't answer me. So what they are telling me all the 3rd party applications have the same fault cause all of them freeze? Why did my other tv's and android media player work fine? Also, I asked which software should I use, she phoned JVC and they told her there is non available in South Africa. We aren't in the dark ages anymore when it co.es to SMARt TV's? They don't know the answer and just passes the buck to not replace my TV with a decent working device. Apparently they also do diamond, Telefunken, hisense ect. Rather spend your money on a decent product in the future and don't settle for these inferior brands.
