Late delivery and poor communication

I ordered from Takealot some time ago. When I ordered I was informed that delivery will take place on 7 December. Nothing happened on the 7th and I received no communication from Takealot. I phoned on the 8th and they could not tell me what was going on. I received an email on the 11th to say that my parcel will be delivered on this same day. Around 15h00 I saw that the parcel has still not been delivered. I logged into my account to track the package but the website would not show my orders. Shortly thereafter I got an SMS stating my delivery has been delayed. I phoned the call centre to get an update. A manager promised to phone me back to indicate when delivery will take place. This has still not happened.
