Lg Poor after sales and cheap quality product

I would like to share my view...I'm truly and absolutely disheartened by LG, I bought myself an Arx8500 a while back around 10/ 2016, almost 2and a half years ago, it cost me R7500 and came with a 2 year warranty....and for that price one would assume it would be a good quality product and hey since it's from a major brand like LG what could go wrong....exactly after the 2 year warranty elapsed my slip even git faded and I threw it away just around 2 years being up then amplifier started giving in, it came on but no sound on some speakers and if you put it loud it goes on protection mode...then as if that wasn't enough, I took it to the lg repair Centre in Pinetown thinking I will get some joy and I paid R170 to book the amp for a technician to asses. He calls me and tells me that one or two IC are blown which I suspected but wanted it repaired. He then goes on to say that they don't do repairs but they replace the entire boards. Yet they call themselves repair Centre. I asked him what's the cost and guarantee on the board and repair, he says its R2100 and 3 month guarantee on what he replaced. I totally lost all faith and respect for LG and their team. Where do I come up with R2100 to replace an entire board which can be repaired at at cost under R400. I've had a Samsung home theatre system from 2006 and it still works beautifully ...and that is the Amplifier system I use the most, the LG ARX8500 was one of those I used once in a while it completely gave up in less that 3 Years...I would urge anyone not to buy any LG products...they are not good quality, you'd just be wasting your money. Samsung is the way to go if you want quality and after sales service.
