Short delivery and no response from Takealot

On 24 October I ordered 2 print cartridges for work (Order number ********** 4). The delivery took place on 27 October while I was on leave. On my return I discovered that only 1 print cartridge was delivered. I wanted to call Takealot about this but there is NO CONTACT NUMBER on their website. So I emailed them and got a response asking if the box had been tampered with to which I rep**** that it was fully intact when delivered. After that, nothing...
