Takealot not fulfilling its guarantee

Bought an ACER Aspire 3 Corei% 1TB Notebook from Takealot in September last year. In April the laptop crashes and can't get it to reboot, o matter what I do, the laptop is dead. I personally take the laptop into the Takelot on 20 April 2021 with return reference number RRN-f57kg-rrr5. After 21 days, I get told that the laptop had a 6-month guarantee through the 3rd party that the laptop was sold through - r A. Computers, and that they will not honour the 12-month guarantee as stated on the website. Of course, the item is no longer for sale and so there is no longer a listing for the laptop. ACER says none of their laptops go out with a 6 month guarantee, so it is no obvious that Takealot is nothing more than an ******* front for Mr A Computers which is a shipping container standing in the middle of Giyani. I want Takealot to give me a full credit.
