Online shop is a ****

Bought a TV on special online and Hi-Fi Corporation held onto the money for over a week without update. Today I received a call from them stating that the item is out of stock. The operator told me that they were calling "ALL of the customers that bought that product" to inform them that they do not have it. Just to recap - they put on a special that they wouldn't fulfil, and they held on to an number of customers' payments for who knows how long. That's *****.
