Like others have said, the best thing to do is to schedule the appointment online. After initial delivery, it took me 3 weeks to get an appointment at the Costa Mesa SC (not to mention I had to wait an hour in my car at the SC before someone came out to note the service requests even with an appointment) and it took them 3 days to resolve the non-critical issues. One issue couldn't be resolved because it took them another week to receive the part. After a week, I had to follow up to see if they received the part. SC confirmed and I was able to schedule a mobile appointment in 2 days time. BTW, mobile service was a great experience.
