Items inexplicably dropped from order

I attempted to purchase 7 items on your website on the 12th of July. The 7 items (Totalling R469, 7 different stock items at R67 each) remained in the basket until the final step in the payment process, at which point the purchase amount that was processed to my credit card became R201 and my order reflected on 3 of the 7 items. I immediately called your call centre and queried the issue. The person who assisted me couldn't understand the problem, so she cancelled the order and tried to process the order herself, unfortunately with exactly the same result. It is now 8 days and a number of follow-up calls from me later and the problem has not been resolved. Through various conversations I've had with your call centre staff it appears that there is some kind of configuration problem relative to the 4 affected items, but nobody seems to know who is supposed to resolve it, and I've not received a single follow-up call since logging the issue last week, all contact has been from my side. I needed the items by the 26th of July, which I have conveyed to at least two of your staff, namely Luedo (don't know correct spelling) and Toefgah. I need someone to tell me when I can re-process the order and by when I will have access to the goods, even if I have to go to your warehouse to collect them myself. All my previous dealings with Takealot have been smooth and convenient, so I really didn't expect the struggle or the lack of service of the past 8 days. I need someone to sort this out asap please so that I receive my goods by the 26th of July.
