Updated: In fairness a lot of this is the fault of apple's booking process and the staff here seem pretty helpful. I get the feeling there is a lot of frustration going around regarding this particular issue.

Wanted to do the iPhone battery replacement. Called CC first. Was told to book appointment online via Apple site. Did that and waited a week for it. When I got there the service desk was busy so waited another 20 min. Then was finally told that the batteries are out of stock for 2 or 3 weeks... left with nothing but disappointment and frustration.
