sick and tired of LGs incompetence

In 2018 I had bought a FH4U2TGP2S LG washing machine. A few months ago it started making strange noises. I had then contacted LG which sent through a technician to evaluate the appliance at my home. After the assessment, the technician, mentioned that the noises were due to unattached parts beating against the washing machine drum. He proceeded to say that this has occurred as a result of bolts/*****s that held them together which had come loose. He suggested a replacement of these parts.... the machine had a defect! The feedback I received with regards to the root of the problem surprised and concerned me. I didn’t think that LG washing machine would have such a problem after a space of two years. When I bought the appliance, I had opted to make a good investment on a name that was trusted. LG is a reputable brand that I too came to trust in. So I would not have expected an issue with loose *****s. Due to that, it led to further damage of the appliance that will cost me R6000 to fix two years later. Looking at the invoice for the work that needs to be done on the washing machine, I realize this amount is almost half of what I paid to buy it. With such an expense I might as well buy a new one. Honestly, I am disappointed at how quickly this appliance has failed and refuse to pay this amount on an appliance that is supposed to last years. The diagnosis of the machine states that this machine had loose *****s? How do you sell a machine with loose *****s? What about quality assurance?

fast forward.... I have been waiting for LG to get back to me for over a month now. They do no respond to my emails and I am sick and tired of dealing with them

how does on escalate ?
