BAD SERVICE! HAVE TO DO TAKEALOT EMPLOYEES WORK FOR THEM

I am very unhappy with the service that I have received from takealot - on the 15 of May a Placed quite a big order with them and I was advised that my order will be delivered on the 21st of May. I found it strange that i did not receive an sms confirming that my order will be delivered on the day. I then reached out to takealot only to find that one of the items i have order is causing the delay. so i told them to remove this item and to credit my account, with that said I have now been told that my order will only be delivered on the 27th of May and there is nothing they can do about this ((they could have communicated (way in advance) that one of the items is causing a delay) why did i have to reach out to the takealot (the supplier) before they could notify me about this?) in the last 3.weeks I have spent quite a penny with them and this is how they treat a customer - will be te last time i make use of them - I will be reaching out to other providers instead ((were I will have to wait for my order)) but it is fine, as long a takealot does not get any of my money anymore :) :)
