Takeallot SA - Shocking Customer Service

I placed an order on 29 Nov and paid in full. Once I received the estimated delivery date I noticed a 3 week lead time, I made contact with customer care on email and requested that the particular items causing the delay were split into a different order so that the items that were immediately available could be dispatched. I received confirmation on email that this was done and that the order would now be shipped. It has been a week and a half and I still have not received my order. I made contact again by email as there was zero feedback, now there is total confusion and everyone that I speak to cannot comprehend what I have requested and simply resorted to a default expected delivery date that was originally received. After explaining again what I wanted to be done it was still not implemented. Now after expressing my frustration at the situation and inability of their staff to resolve a simple situation it seems I have hit a brick wall, with no indication of when I will receive what I paid for.... It is very inconvenient trying to plan to receive my package, on the website it states the order will be delivered on 9 Dec, but still nothing, remaining unsure of when I will receive my goods.
