Can Takealot handle and exception?

I bought a pair of binoculars from takealot and after delivery proceeded to request the invoice. I was notified that the invoice was available and when I looked to print it, I noticed that the invoice had the wrong items on it and was for the wrong amount. There is no way to 'query' an incorrect invoice on Takealot using their web processes so I used the ORDER query to query this. Siyamthanda responded asking me to send a copy of the invoice, which I did. Next I got an automated email stating my invoice is ready, and again, it was the wrong items. On 23 June, I responded to Siyamthanda's email trail stating it was wrong but I received no reply. On 26 June I followed this up on the same trail - no response. I have now been trying all around the Takealot Website as to how I can complain, or query or escalate an unresolved issue but I cannot find any way to do so. It seems as if this is not an option.

I have spent over R6000 on this item and I have no invoice for it - this is not OK.

My complaint here about takealot is that my query is unanswered and that there are no clear or obvious available 'help' or 'contact us' options for a general query, or an escalation, or an un resolved issue.
