Hi-Fi Corp seemingly doesn't update their stock

Ordered headphones from their online shop. Paid in full and waiting in anticipation I got an email 2 days later informing me that the product is out of stock and will not be restocked. On top of that I was told to wait 7-14 days for my refund. As a student who was saving the cash for the headphones I now have no cash to buy a different pair while I wait for my refund. After being so eager to take my money it seems a little disingenuous to not try and get me the item (that they have at a warehouse that apparently does not travel to my area) and then tell me to wait for my own money when they did not have to wait on mine. Be careful of their online shopping option, they do not update their stock it seems.
