Very disappointed with defy, forcing people to use they products by force

Very disappointed with defy bought a washing machine October 2024, the machine started making sounds on December they sent through a technician to take the machine to the workshop to fix it they brought it back same day the following day when I used it, water was going through the machine non stop called them again and they fix the water problem but the sound was now worse,called them again December the technician checked it and said it's fine but the sound was still there called again when the technician came I told them I no longer want the machine because they can't fix the problem. Been to the shop several times they kept on sending the technician of which is not helping me its like I'm being forced to stay with a broken machine of which it started give me problems within 6months of being bought till today when I called the store defy still wants to send a technician to come and fix the machine of which I made it clear to the store and the technician that I want my refund so I really don't know because I even reported it straight to defy they also send through a technician on February now its April defy still insist on sending through a technician even if I made it clear that I no longer want de machine because they failed to fix it.I don't how many time the technician has been to my house and there sound its still there and I don't know how many times I have reported the machine without any help from defy
