What has happened to service delivery in SA?

I placed an order on the 8th of June and paid , after I reviewed the order I realised I've selected the wrong item , or an item I didn't want to add to the basket...now people gonna say how does this happen and you had to confirm purchases bla bla bla.Still here lies the problem, there was no cancel button available and when I immediately emailed take alot to ask to cancel the first person said do I want to cancel or swap out a certain line, then I said please cancel only one line and add the thing I actually want, I even attached and screenshot of everything.Then comes the second person and says sorry we can't amend orders and then the third person comes and says sorry we can't cancel the order as its been authorized aaaaaaand then at my utmost disgust with the process a fourth person mails me and says they can only cancel the order when I get a delivery date estimate , otherwise I need to reject the delivery, if one should do that they gonna blame me for the charges and I cancelled the order even before it was processed.Why the hell do I need to work with 4 different people with different stories to cancel a order and yet no final result.I've been one of those loyal Takealot customers who always gave such a great review when my customers and friends ask what is my experience, but after today I'm fed up, I'd rather use Amazon
