Today I had a bit of an issue with a song I downloaded from the iTunes store. Every time I tried to play the song, iTunes shut down. The song was on my hard drive and had downloaded fine, and played fine in Windows Media Player, and Winamp, but not iTunes. This was the third or fourth time this had happened, so I emailed Apple customer service.
They were brilliant. They replied to my query in a couple of hours, told me exactly what I needed to do, and the whole problem was solved with no problems. Plus they refunded the money I'd spent from trying to download the song again.
Bravo, Apple customer service. Well done. Keep up the good work.
