Bad service

I bought a tumble dryer from Takealot and used it twice. During the second time of use it started burning. I wanted to do a return replacement only to get reply that this item on not refundable. I was told to contact service provider which in this case is Mastercare. They want to know if I have a service contract. This is a brand new machine with a 36month guarantee. Anyway besides that they want the invoice. I contact Takealot for the invoice and they send me the invoice. I open the email only to see that they sent me the invoice for the dog food I bought. Now please. I need help from someone
