No delivery after 6 days of order

I purchased a washing machine from makro online the 29th November. The email was received confirming delivery for the 2nd December. Since then I received one email confirming they are running behind on deliveries.calling the call centre to check what happened and they confirm it takes 2 to 5 days to deliver. My husband drove to the Springfield branch where the item was supposed to be delivered from and the lady tells him there is no stock. Yes still no response from makro after 3 emails. So now we are inconvenienced to go into the store and request to speak to a manager regarding a refund? Where is the item how do you Purchase an online item if there is no stock. Customer service is terrible and there is no communication. What a waste of time and money. Refund me as fast as you deducted the money.
