Poor service

My delivery was scheduled for Monday 4 December. The day came and went and I received an SMS that my delivery was rescheduled for the following day. The same happened that day and the next day. 3 times it has been rescheduled. Call centers say all they can do is reschedule it yet again. It is now 7 December and still nothing. I am strongly having my doubts in Takealot.com No one can tell me where my parcel is or what is going to be done to rectify this.
