Disappointed!!

Clicks, please explain to me how your online shopping portal works. I have ordered an item during black friday, my account was debited, everything was in order and then a few days later I get an email saying that you want to refund my money because you're our of stock. Does your portal not update that there is no stock left. Also if it was communicated to me immediately I could have purchased the item in-store or somewhere else. According to the CPA, I need a resolution. I don't want my refund, I want the item at price I could have paid for it...I will not take a refund only to purchase the item at a higher price when I could have purchased it at a lower price.
