3 months and still no refund received!

i purchased a fridge online on 16 May 2020. The item was meant to be delivered to my home. By 28 May I sent an email requesting when i would recieve my item. recieved a automated response with no definitive outcome. On 03 June i requested to cancel this order, as i urgently needed the fridge and made alternate plans to get one. i recieved confirmation that my order would be cancelled and i would recieve a refund. On 20 June i recieved an email advising that my order is on the way, I immediately called the call centre and the consultant advised that the order has indeed been cancelled and the refund will be processed. On 23 June i recieved a call from the delivery agent, who advised they were on the way to deliver the fridge! I advised that the order was cancelled and they left with the fridge. On 25 June i recieved an automated email, advising that the refund is being processed and might take up to 14 working days to reflect on my side. We are now at 28 July 2020 and i have still not received my refund. I have sent numerous emails with no response. This is ridiculous and unacceptable. This is definately the last time i do an online purchase with Makro! Very dissapointing service!
