Makro Refund Never Received

I honestly am having the worst experience with Makro, I placed an order on the 8th of September paid for the order received the confirmation email. A week later I checked the status of my order, and it showed cancelled i called Makro and they advised that my order was cancelled due to no stock and i would be refunded withing 7 to 14 working days ... Today is the 13th October and i still have not received my refund , i have called emailed and even used the WhatsApp chat to try and get feedback on my refund and i just keep getting the run around or told that there's an error on their side and they taking it up with finance and someone will call me which never happens , i called them again today and all i got was a sorry and someone once again will call me to assist . This is ridiculous service why should i be calling after my money and keep following up on my refund.
