Complaint

I bought a tumble dryer from takealot. I have used it twice and it burnt out. My whole place was filled with smoke. My son in law reported a return claim as he had made the purchase on my behalf. Upon enquiry he went and checked on the progress of the claim only to see that it had been closed. He then viewed it only to see that this brand new machine will not be replaced and I have to contact the agent. I contacted the agent and they are mastercard and they do repaired and also they need an invoice. Now my question is this is a brand new machine and it should be replaced. Secondly I am battling to get an invoice. I emailed takealot and was told to click on accounts and then invoice on the app. There is no invoice icon. How am I going to get this resolved
