Very disappointed with the service I received from Makro

Very disappointed in Makro, I ordered a hoverboard online on the 9th, I recieved a call 2 days later from their supplier to advise they so not have stock of what I ordered, My question to them how did the system allow me to place an order of what you don't have stock on. She then advised that they have it in order colours but not in the colour I wanted, she sent me pictures via what's app so I could see the colours she has, upon receiving the pictures I realised what she has is completely different from what I ordered not only the colour but the features as well. On their website it was even priced cheaper that what I paid for the one I initially ordered, when advising her of that she insisted it was the one. Fast forward, I ended up asking for a refund as she was just not understanding me, she then advised me that she will chat to her manager and get back to me of which she never did, been following up on my refund with her but never received any responses, I decided to call Makro customer care and the gentleman I spoke promised to follow up on the cancellation and refund and get back to me which never happened. On the 20th I get a what's app text from the lady that has been handling my order advising that my delivery is on the way, I asked what delivery because I asked for a refund? She advised they received stock of what I ordered. To my suprise this morning they delivered the less priced on, just the colour I wanted but the features are different. This is supposed to be a Christmas gift, the cancellation and refund process is gonna take long, what do I do.
