Poor customer service and disfunctional washing machine

I bought a washing machine at branch 4770 Katlehong OK furniture at Sam Ntuli Mall on the 17/06/2020. The machine was working perfectly fine up until the last week of November 2020 meaning it worked only for 5 months after the date of purchase. On the 28/11/2020 I realised that the tumble dryer wasn't working anymore and I called the store to let them know that I was encountering a problem and they assured me that they will get back to me and send a technician over to have a look at it, which never happened. I ended up going to the store on the 10/12/2020 and Thato was the one who got to assist me and that's when they took me seriously and logged a call for a technician and promised to assist me. However I waited for a technician to come by and he only popped in on the 24/10/2020 and said the motor is broken and he will order a new one and come fix it. In the meantime I had to wait with a washing machine which wasn't working. The machine was only fixed on the 07/01/2021 meaning I waited almost a month for the machine to be fixed. The machine got broken again within a couple of weeks of it being fixed and I again went to the store on the 15/02/2021 for the same problem and they said they will follow up and call Hisense using the initial Ref number: ***. I have been waiting ever since, no feedback, no follow has be done till today. I am so truly unhappy and disappointed with the service I got together with the non functioning washing machine I have. It appears the machine has a manufacturing default because it's not possible that a machine can break twice within a period of 8 months of purchase, I mean I bought that washing machine cash thinking it will make my life easy instead it's miserable. Kindly assist I want my refund.
