Terrible Disappointment in After Sales Service

I cannot believe I am doing this review, as I have always been a regular client of Takealot. But after 2 attempts to get assistance from their customer "service", I do not know what else to do. I am currently on leave (Friday, 6 Jan), but returning to work on Monday, 9 Jan. I placed an order of R800 on Wednesday, 28 Dec. When I checked out, the delivery date was indicated as Wednesday, 4 Jan. I live in a main centre - Cape Town. So I picked my home address as the delivery address. Both my home and work addresses are saved on my profile. When I saw that the delivery date changed, I sent a request for assistance asking if my order could perhaps be delivered on Saturday, 07 Jan OR if I can change my delivery address. Zoe rep**** that they cannot assist with that date, I must reschedule. No answer on the change of address. Until today, when it ARRIVED in Cape Town and I received the SMS that it did, only then did I have the option to reschedule another date. I figured I will then have to wait until the next Saturday, since I know for a FACT they also do Saturday deliveries. Yet, no option for Saturday, 14 Jan. I again sent another request for assisrance, explaining I cannot receive my order at my home address now and asked for it to be changed to my work address. I supp**** the addressed that is already saved on my profile!!!! I got a reply from Thimna saying they cannot assist me. So what now???? Am I just going to throw R800 in the water and Takealot just shrug their shoulders?????????
