Unsatisfied Client about Washing machine

I bought a washing machine on Credit. The pulsator inside the machine broke, I phoned Lewis Phalaborwa to submit the claim for the repair. I waited 4 weeks for them to repair. They did repair and brought the machine back, I used the machine 2 days, the pulsator broke again. I phoned thw Monday and lodged the complaint and I was told they will come to collect to repair again and I told then NO I WANT A NEW MACHINE. its a month later still no Machine still no New Machine. When I call they tell me everytime We are still waiting for HEADOFFICE. I HAVE NO MACHINE MUST WASH IT WITH MY HANDS OR A WISHY WASHY. NOT ACCEPTABLE. My account is paid everymonth I am not behind with any installments.
