Game and Hisense have horrible customer services

I bought a washing machine from Game Cape Gate in July 2018. The machine broke down in September 2018. It showed an error that is not even in their manual. I reported the fault the following day -5/09/2018. Then they sent a technician after numerous calls and emails to game. I was assisted by Brandon who would always get back to me as soon as he receives my email. On the 19th of September, I still had to follow up as there was no action from game or Hisense. The technician finally made it to the house, to look for pins and coins in the washing machine pipes which he did not find and he said that the should be something with the computer box. He left and I never heard from them again. A week later, I contacted Game for assistance as I did not have the supplier's contact details and the informed me that the supplier is still waiting on the part and they would contact me as soon as they have it. 2 days passed and the technician just pitched at the house unannounced and as expected, there was no one at the house and I asked him to come back the following day and he agreed. I stayed at home waiting for the technician to arrive only to be told later when I called to ask where he is that he was not working in my area and this was not communicated. He pitched the following day with a new computer box, he replaced it and the machine still didn't respond to the newly replaced part. I then asked them to stop coming to my house unless if they are coming to collect the washing machine. I asked for my refund and Game is not responsive. I just want my money back, I will never ever buy Hisense products ever in my life. They must work or else give their jobs to the poor South Africans who are willing to do the job. Game Cape Gate and Hisense are just nonsense. This has been the worst experience I have ever had with suppliers and a store.
