Unprofessional service, and no refund

I made an order online with Game stores (order *** ). By the next day I receipted a mail saying the item is with couriers. On the 12th of August I received a mail saying I have received delivery of my item. Which I obviously did not, because I would'nt waste my time calling the useless call center 4 times for my item if not. So 13 days after the order; whilst in contact with websupport via mail, I was told its all an error and there was no stock, nothing was actually dispatched. So websupport told me I would be refunded, I said fine and I expect it will reflect in 3 to 5 working days (which obviously again it has NOT). So when can I have my R724 back for the item that were delivered to someone else? I have been inconvenienced as I needed this for working from home, plus I wasted my time on emails and calls, and now I am still out of pocket for this. Ridiculous. Do you think we have nothing else to do?
