Pathetic Service Game Mall@Reds

Purchased a Samsung Washing Machine 8KG from Game Mall@Reds 19/02/2022. Machine never met my expectations. I misplaced the receipt as I needed their help as machine is faulty. To date I'm told they can't trace the receipt. I'm stranded with a machine I can't use. I take my clothes to the laundry. Game requested serial number and model number of the model on 16/11/2022, they promised to get back to me which they did not. Called their head office as they requested proof from my bank to proof I bought the unit from them. I gave them the proof and was still not contacted by the store as promised . On the 18/11/2022 went physically to the store and spent Over 2 hours while they tried to look for the receipt and the lady said they will email it. To date they can't get the receipt. They keep saying they will call me back as they want to ask their Manager what to do. Their manager has not had the decency to assure me that it will be sorted. I don't think this is aligned with CPA. From the day I bought the machine there was a problem, I did call Game head office to report the lady who was assisting as the transaction took for ever to a point I had to go back the next day. It's possible they sold me faulty machine deliberately as I complained of the service from day one.
