I ordered a Christmas gift from Makro's website on the 4th of December

I ordered a Christmas gift from Makro's website on the 4th of December. No notification was received that the item was no longer availible but I was still charged the full amount. Only today when I went into their page I saw that the item went out of stock and the refund for the amount is only to be expected on the 24th of December. Considering the time of my order, lack of communication as well as the unnecessary strain placed on me from a financial, as well as effort to source a new gift perspective, and the fact that this refund now only happens on the 24th December, leaving me no time to get my child a new gift. I made contact with the Makro call center today and was promised feedback today and received none. This further compounds my frustration. Previous returns to Makro only took 7days to refund. I find this highly unacceptable, especially over the festive period. I need a resolution and my money back to be able to get my child a gift for Christmas.
