Defective & Faulty Washing Machine & Poor Customer Service

I bought a Samsung washing machine on 27/11/2023 and reported to the store that the washing machine does NOT take out simple dirt on clothes. This complaint was reported early December 2023. They sent me a technician mid-December who came and found me doing laundry on the day, he took pictures of the defective washing machine and even took pictures of the clothes I had washed still having dirt and he said he would come back January 2024 when their offices reopen. In February 2024 when I followed up, I was informed the complaint was closed and this was without my knowledge. I complained about their poor customer service cause how do you close a complaint without resolving the problem nor informing the person complaining?! To date, I keep following up with SAMSUNG but they keep stalling for no reason to assist me. I need my refund because I am tired of using a defective washing machine and running after your customer service agents because they never bother to give regular updates on my complaint. You are aware I am aggrieved but you still allow your staff not to attend to our complaints to give simple updates. I have a LG products and have not experienced such issues with their products and their customer service is far better and your could learn a thing or two from them. I am NEVER buying another SAMSUNG product never!
