Fail to honour refund and refuse to escalate issue

I returned an order from a 3rd party seller that "short delivered" on the items ordered. I ticked "Replace item" instead of "Refund" by mistake. As soon as submitted the request I phoned them and asked them to change to "Refund" and received confirmation mail stating that was done. A day or two later I received an SMS that my replacement has been ordered. I phoned again and with great difficulty got them to realise that I do not want a "Replacement" and it was logged as such on the system. The answer was "They will correct this and get back to me." All this started on the 22nd and I am still waiting for feedback or a resolution. I've mailed and spoken to 5 different people since then. I asked for the issue to be escalated to somebody higher up and that has not happened either. What I did get is a SMS stating that "they could not deliver my order". I never got an SMS saying that is "out for delivery" and there is always somebody at the delivery address so they ****. The latest "BS" I got this morning is that they need the 3rd party seller to action this which I do not understand. If Takealot *****ed up the process they must refund me and then it is their problem getting the money from the 3rd party seller.
