Worst after sales service ever!

I bought the best microwave model 5 years ago paying R7000 for it. Today it is worth R13000. Shortly after I bought it, it started giving trouble. While under warrantee, I sent it back for repairs. 2-3 weeks later I got it back without any explanation about what was wrong. The reason for no explanation, I would discover a few months later. Seems I bought a dud and LG will simply NOT take responsibility for that. Somewhere in the front electronic panel, there is a poor connection. The microwave will work for months and then just suddenly at random times, it powers off. At some point the electronic button made a sound like some wires are sparking. Fact is, it's VERY difficult to take it in for repairs. Two or 3 years ago, I took it in again to the LG service repair center in the Cape Town northern suburbs. Just like last year, I took it in again at another LG accredited service provider. Of course, I had to pay again for the evaluation. And guess what? LG repairs could once again not find the fault. This really left me annoyed that I have to keep on paying for fault finding, which they don't find, then insinuating that there is something wrong with either my mind or my plug, "because they have done a thorough check" . They even asked me to take a video of when the microwave switches off. Hey, I told you, it happens randomly. I don't get to predict when it will switch off. I just took it in again. This time to another service provider because the LG providers are rude, demand payment for services not delivered, and when I report this to LG, they don't even have the courtesy to follow up with me. No, instead they just posted a reply to ME, but speaking to the TECHNICIAN as if I don't frigging exist, to check and NEVER bothered about my complaint that the problem didn't get fixed. I refused to pick up the microwave last year unless they FIND THE FAULT with which I am struggling for 5 years to fix. And then they threatened me that I will pay storage for an appliance with which "there is nothing wrong with". Now again I took it in for service. This time at a non-accredited LG service provider where I paid R3000 to replace the element that broke. I asked them again to check why it powers off. They could not find the fault either. Back home, the microwave cut out again. This time it won't come back on. (note, if I do move it, chances are it will power back on at the service provider and they won't find fault). But LG, guess what? The non-accredited service provider is willing to send out a technician for free to my house to come check. Quite a contrast to your rude and your rude service suppliers' attitude. When someone buys a product at the high end range, you'd want some better support, some better experience, some better after sales service. NEVER, NEVER again will I buy from LG again. I guess Samsung will be the better option. At least they have DECENT walk in centers where you are treated with some respect and dignity, especially considering the "quality product" I bought.
