Sometimes you just walk-in and we are still attending other visitors. This is the reason we prefer online appointment. But, we do not strictly ask to schedule appointment.
If you are in a rush and want to drop-off your device and pickup when ready, that is fine with us. Do it please. Any day. Or any time during our regular office hours. You can give us a call at 800.521.6181 and check with us if you can simply walk-in at your own convenient time.
