I need a battery replacement for my iPhone 6s. Micro Center Tustin is listed as an authorized service provider for this, and appointments can be scheduled through Apple Support. But... I specifically called the number for the Tustin store listed on the Micro Center website and inquired about a battery replacement. I was told that the store does not take appointments, and I should just show up at the Service Desk. So, I took my lunch hour to drive to the store, wait in line at the service desk, only to be told when I reached the front of the line, that they don't have any batteries in stock. What? It would have been nice if they had told me that on the phone. Idiots! I'm not impressed.
