Poor delivery service

I made an order and payment on 28Nov2019 and my order is shipped in separate parcels, I never know when the next one will arrive. Takealot said that delivery will take place by Monday 9Dec2019, I only received one item from my order on that date. The next item arrived on 10Dec, and I'm still waiting for items that I ordered. Why should we wait so that the whole order is filled before shipping if it is not even shipped as one parcel? Now I never know when my parcels are arriving and I dont know if it went missing at this time (the call centre also does not know). I called the call centre and they said they will provide feedback but I have not received any indication of where my package is. Christmas time is comming and we are traveling so late delivery means that the delivery address is going to be a problem. This is unacceptable. Do not promise to deliver a service by a certain date if you are not able to do so!

I am very dissappointed at this stage.
