Makro not honoring transaction

I purchased two printers online on Black Friday even got a message stating that my order has been confirmed. Today the 4th of December I received a call from Makro stating that they don’t have stock of the printers and want to refund me. I told the lady I don’t want a refund I’ll wait for the stock, after going back and fourth she told me she’ll find an alternative and let me know. With no call back I received an order update that a refund is due. Makes me think thier Black Friday deals were ****s.
