Makro Online

I have received bad service from Makro Online, I purchased an item and paid for the item later on that day I was informed the item wasn’t available the order was cancelled I waited for the refund for 7 days until I decided to call them and was advised that there’s nothing the can do I have to wait for the refund for a further 14days. My thing is that I never cancelled anything , they are the ones with an app that’s not updated and I’m now made to suffer when I need to purchase the items elsewhere, it’s frastrating because no one is communicating with me about this and when I call to ask for the finance department no one is willing to transfer my call, I’ve been calling since the 10th of October for an order they cancelled on the 4th of October still after so many escalations no correspondence has me made to me!
