Bad service and no delivery received

I placed an order 25 January and selected for it to be delivered Saturday. Please keep in mind it is stated "guaranteed weekend delivery" which did not take place due to technical error. Then it was rescheduled for Sunday and again there was a problem only this time with the courier. The depot the parcel was sitting at is in Alberton which is where I reside (my delivery address for the Saturday delivery).

I logged queries to change the delivery address to my work address in Germiston for today and I haven't received a response to these queries, so I called in and spoke to a consultant who had to speak to the Alberton depot and they cannot deliver to Alberton. I then sent the consultant another delivery address for Alberton and now the query has to be referred to that branch. Why am I being put in a position to accommodate Takealot when I as the customer should be accommodated due to the inconvenience of not receiving my parcel when I was supposed to?

This service is utterly shocking. This is a R2000 order. I need this parcel delivered today. I specifically wanted it over the weekend as it is a birthday gift. The birthday has come and gone and no parcel.

Management needs to resolve this for me today. Customer service needs to be shaped up here. I worked in customer service for years and this is not the way to handle things especially since the problem came from Takealot's side on two occasions.
