Bad customer service and bad quality

I bought a washing machine on the 17 January 2023 and it was delivered the following day on the 18, when delivered we opened it with the driver to see if everything was the,in order and all was good. Sunday the 22 we dicide to use the machine to do laundry, the machine doesn't work, it turns on fine does all the settings and even put water inn but when it has to start washing it doesn't. On the 24 January I called the store to make a complain I was transfered to speak to Walter of which he never answered the phone since he was busy on the 26 I dicide to go to the shop to complain about the washing machine I was approached by a guy, I showed him myself and explained my problem he then told me that the only person to assist me it's Walter so he went to the back to call Walter but Walter was too busy to come and assist me he told the guy to tell me that he will call me before the end of the day after four hours I went back to the store to see Walter but he was still busy. I waited for Walter's call until I dicided to call him after 2days and still Walter was too busy as usual I've tried to talked to the store assistant manager but she didn't care she didn't even want to know she was just not interested in what I was saying she just told me she will tell Walter to call me and after few days I got hold of Walter but he didn't have anything to tell me he said he will make a follow up since he did login a complain and he will call me in 30 minutes and that was Wednesday the 2 second of February 2023 as I write this its Saturday the 4th February still waiting for Walter to call me back and I'm stuck with a none working washing machine that I have paid R8000 cash plus transport money ontop. I'm so disappointed with house and home festival mall and the hisense washing machine I'm so mad and just want my money back
