Lewis bad service

I bought kelvinator washing machine on 04 April 2023. I started using the machine in February for the first time, it started showing default the second time when I wanted to use it then I went to the shop and lay a claim in mid February, claim number (T***) . They send the repair team to repair and the repair team also took time to fix it. I went back to the shop the following week that was when they came but it didn't take time before it broke again. I also went back to the shop to lay a claim on the 19th of March and they asked me if I was going to be available on that Friday. After confirming with them that I will be available as the schools will be on recess. I waited till yesterday when I decided to go back to the shop, to ask about the progress of the claim. The lady at the branch who works at complains department she really tried to help but she could not get positive feedback from the head office about my claim. Yesterday (15 April 2024) after I had a conversation with the lady I got the call from repair team that they were called to collect my machine so that it could be fixed again but I denied. The reason is because the machine would be fixed for the second time so what is going to happen if the machine breaks again and the warranty is over. My case is not been attended to properly because it's been a month now without a washing machine and I am still paying full instalment monthly. I suggest that they must give me a new machine or else give me a refund.
