A shop that needs to be managed properly & products to be shipped on time or stated as OUT OF STOCK

brought a breville coffee machine on the 19/8, saying it was on the clearance shop it will only be 1 working day, but waited until the 7th day that i called them up and they said it will be going out within 12-24 hours.. yay but no...
Next day i called saying "whats happening with my order?" oh we dont have any in stock.. and wont be until September so i asked for a refund. I have checked my email to see if they have emailed stating that the order has been canceled but havnt and the site has not been changed.
Would like to get a email telling me that i have canceled my order and will be getting a refund.

Website needs to tell customers when products are not in stock.. and to get a call or email after 1 working day when things are late!
