Lack of Customers service

I bought a laptop from takealot and on the 12 Jan i returned the laptop as it was making a breathing sound when i charge. i logged my return and explained reasons for return and asked they replace the laptop with a diff brand of the same value of money i paid. Takealot has declined my request and saying there is nothing faulty with the laptop however they have not returned the laptop to me. i responded to an email i received from Nazmeerah and i have not received any response to date. I have been inconvinened due to their lack or sense of urgency even after i explained to them i need this laptop for my son as schools are open, every time i call the call centre they tell me they logging a request with the warehouse and will cc me in that mail, to date no mail has been received. im disgusted by Takealot's lack of efforts to assist me with my query and at this point want a full refund and i will purchase a laptop from a reputable store
