Washing Machine Refund

My husband bought 21kg LG washing machine online, it was delivered on 6th July, we called Makro on the 16th complaining about this washing machine giving us problems, they said it's still within the 14days we should send an email and mention which alternative washing machine do we want, yes we did that and unfortunately the alternative we wanted which was Samsung 18kg, they had mentioned that don't have it and therefore will refund us. While awaiting on that an LG consultant calls sent by Makro to send a LG technician to check the washing machine, I made it clear that I don't want the washing machine to be checked I want them to collect and refund us, she told me I should let Makro know of which I did immediately, Makro advise they will collect and refund us. Some lady from Makro called on the 23rd July from Makro Strubbensvalley saying they'll collect Wednesday the 25th July, no1 came to collect to collect, to this day I'm still stuck with the washing machine and Makro has been giving us a run around in resolving this matter, now we back from the start, they saying they will send a technician before they can take it back. I don't understand why should they even go back in saying they'll send a technician after I've made it crystal clear that I don't want this washing machine, this whole process is dragging unnecessary and very inconveniecing, it will almost be a month now stuck with a washing machine we don't want. All I want is for Make to collect their washing machine and refund me as in yesterday.
