Unimpressive for a leading tech company

I placed an order for a Macbook on the iStore and opted to pick it up from a store nearby in order to receive it ASAP. The site reflected that stock was available at the store, but an hour or two later I received an email from the store stating that they didn't have stock available but could acquire a unit from another store in a day or two. I tried calling the number given to find out if I could fetch it myself from the store they'd be getting the unit from but I reached a call centre without an available agent anytime soon. I tried the Chat option on the iStore website and eventually reached an agent who told me that there is no stock in CT and that I'd have to wait 4 or 5 days. The iStore reflects that stock is available in 6 of 7 CT branches, with one of them showing "limited stock". I would have expected the official SA site of the world's leading tech company to be able to put together a web system that can reflect current stock statuses. 5 stores are out of stock without yet even reaching a "limited stock" status? The agent told me that I should call another nearby branch to find out if they have stock and if so she would give me a voucher. The number goes to another call centre and for some reason she didn't respond when I asked if there was a way she can directly herself.
