Good day, Could you please assist me with the following matter

Good day, Could you please assist me with the following matter. I bought a Wasing machine from Game on 31st May and in the first week of July I contacted games complaints department this washing machine is leaking and they sent technicians more than 6 times the technician told hisense they need to replace the machine and yet they refused to, I asked for a replacement and they refused the technician came to collect the washing machine. I then got it back a week later in very poor condition they said they will not replace the machine it's working fine and they said it's water pressure. This is not the water pressure and I can provide proof of all this. Please assist me in this matter I would like a refund. This has been going on for weeks and this is clearly a faulty washing machine.
