Terrible service

I bought an 8l airfryer on 4 September and a month later it stopped working. It has a six month warranty. I logged a return twice and both times it was returned to me with no action taken. I was told to contact the customer service dept and was told I had to contact the supplier which I duly did. After many fone calls backwards and forward the supplier is happy to replace it but has told me that takealot must contact him to return the defective airfryer. Takealot has again refused that request and I still sit with a broken airfryer under warranty
