Change delivery date by 3 days without notice

I placed an order on 8 Oct 2019 for 2 x Mini Wireless BackLit Keyboard & Mouse Combo - Black which was sold by ***. I paid R276 on the same date and the delivery date was set for 11 Oct 2019 so I opted to pay R60 delivery. On 11 Oct 2019 I logged into the website and saw that the delivery is now 14 Oct 2019. I wasn't notified and want to collect rather for R25. Takealot do not have a customer care number to call or an email address on the website and it makes it difficult and frustrating. How is customers complaints resolved? I want to fetch the parcels at Alberton today for R25. The R45 courier fees must be refunded.
