Takealot collection simply not happening

I logged a return last week Wednesday and was sent a sms saying the following.

Hi Peter, your Takealot return RRN-9ABD-583F for order # ********** 1 will be collected before 5:00 PM on Thu 20 Dec. Not convenient? Call ********** to reschedule.

There was no delivery on Thursday. I contacted takealot via phone email and social media. Was promised the collection will happen on Friday. Same story on friday and absolutely guaranteed collection for Monday 24th. So no collection and every time I contact them I have to explain the entire story again and I get told the matter will be escalated. So now I'm escalating to posting this in the hope it actually resolves the problem.
