Money Paid but no Goods to show for it. Unable to fulfil the order yet Crocs SA is dragging their heels in refunding me MY MONEY!

My interaction with Crocs SA has to be the worst shopping/service experience I have ever had. I purchased a pair of shoes on the Black Friday Sale, the following Monday I received an email informing me that they no longer had stock of the item I had ordered and that I could select a different style. I did not like any of the other styles on offer and therefore requested a refund. I have messaged you on Facebook, I have emailed you numerous times....I did get an email or two back this gave me hope that I would soon get my refund...but no payment has ever come through. It has been 2 months......as I have no item to show for my payment. Your service is beyond shocking, I will never supporting you again. Refund me my money!!!! Order number: 21188
