I had a bad online shopping experience

I would like to express my disappointment with Makro online. I love and respect Makro, I have been their customer for years. However, I recently had a horrible experience when shopping online. I bought two items ( a lawnmower and a built-in cupboard) on 12 December 2025. The status remained as in progress for a few days. Then the status was not changing for 3 days, I wrote an email to them on 14 December to check when they will most likely to deliver and explore the possibility of fetching one item ourselves since we needed the lawnmower urgently. I received an automated response only. I called the number ***on the day and the following days. I even called Makro Wonderboom, there was no response. When I checked the status online on 18 December, it said the order was cancelled and that I will be refunded the money within 2-10 days. I went to Wonderboom to enquire, they mentioned that the goods where supposed to be delivered from another branch/store and that the online system shows that they (the other branch/store) still have stock. The gentleman at Wonderboom indicated that at this point I must just wait for the refund as that status cannot be revoked. I am still waiting for the money to be refunded. I used my other funds and purchased the lawnmower directly at Wonderboom and ordered the built-in from elsewhere. I am not happy that to this day,nobody has bothered to contact me and explain why the order has been cancelled and I am also not happy that since the order was cancelled on 18 Dec, I still do not have my money back. I think they need to be mindful that if I didn't get the items from them, I need the money to look for such items from elsewhere and process the refunds quickly. Since the online services does not pick up the phone nor answer emails, how sure am I that I will get the refund within the stipulated period? I wouldn't have come here if someone contacted me and explained the situation.
