Shocking. Keeping my money for a month and failing to deliver

My order was cancelled by Makro after three weeks of me waiting (while they sat with my R12k for three whole weeks). I didn't even receive an explanation, just a message saying that a refund was initiated. I have waited a week so far for the refund and have been told I'll wait another two weeks for it to reflect. So by the end of this they are expecting me to be happy with them sitting with R12k of my money for a month and a half over an order that they messed up and failed to deliver. I don't know what's happened to the Makro that it used to be but I certainly won't be hoping there any time in the future. And now when I emailed customer service complaining about the order being cancelled because they were out of stock - a whole three weeks after I placed the order- and requesting an immediate refund since this was their mess up, they just rep**** "we will cancel your order". Like they didn't even read my email. The order has been cancelled already. By Makro. I just want my money back.
