MAKRO ONLINE SHOPPING NIGHTMARE

I bought 2 items online on 21 July 2022 from Makro to be delivered in Kimberley. On 22 July 2022 to order was ready to be delivered in Cape Town. On 25 July 2022 I cancelled the order and was told a refund will take place within 10 business days. It’s 22 August 2022 and I still have not received my refund. Makro is keeping my money because they cannot confirm where the items are with their Courier services. Why must I wait for my money and how long will I have to wait MAKRO?
