********* business practice from Makro

I purchased a laptop online because your website showed that you had stock. After an hour of ordering and getting the order confirmation, Makro cancelled the order, saying that they were out of stock. They then sent a mail to me saying that my refund will be processed in 7-14 days. How is this ethical? Makro falsely claimed to have stock of the item, then they accepted my order and my payment, only to then cancel the order an hour later. Even worse, I now have to wait 7-14 days for the refund to be processed, all because Makro made a mistake. This is both unprofessional and ********* from Makro. I encourage all potential buyers to think twice before ordering anything from Makro online.
