Makro shopping app.

I placed a order on the app on the 26th of October, a birthday present. Delivery was 7-10 working days. Received a mail stating that colour was out of stock. Would I want this or that colour. Ordered a specific colour for a reason, so I rep**** asking when it would be back in stock. I mailed and phoned every day, they merely stated the third party supplier is not giving feedback. They even gave me the third party supplier number so that I could contact them. Phoned the third party supplier and they were not aware of my order. After that amd the fact that I realised I would not receive the item within the eta, I called and mailed to cancel the order, yet 3 business days since, no one has confirmed cancellation, the app still shows order confirmed. This is by far the worst service I have received. Today has been 10 business days, I dont have the item I ordered or my money back. Every time I phone someone promises to assist me and phone back, I have not received one call or e-mail in response to any of my queries.
