No guarantee on 2 month old vacuum cleaner

Purchased a vacuum cleaner 11 August 2020. Some two months later after using it for the eighth time, the centre wheel fell off. Returned the vacuum cleaner 7 October, to have it repaired under guarantee, or get a credit to purchase a new vacuum cleaner ref.PRN-c54_23-a6. After being flooded with countless useless emails, I was told today, 13 November, some more than 5 weeks later, that it is actually all my mistake and Takealot will not take any responsibility. The fact that Takealot does not reply to any Hellopeter reviews, clearly indicates that it is their chosen business model, not to honour any agreement and guarantee terms.
