False information and poor service

My wife bought a coffee machine online. Paid for it and everything. This is what she wanted as it was her Christmas gift. Only to be notified 2vdays later that Makro is canceling the sale as there is no stock available yet the site showed 2 items available at the time of sale. No contact made from Makro, only a mail saying sorry deal canceled, money will be refunded. This is not exeptable why show to items on hand only to take ones money and then to notify that there is no stock. Dealing with Makro for long and never had to experience this level of service.
