Queue numbers have to be obtained through logging in to their designated wifi. After which you will receive an sms notification on your number and service representative. The display of queue numbers are not very obvious but the sound alerts are loud enough. It can be quite confusing for the non tech-savvy but there are staff around to assist.

The staff serving us is really polite, willing to go the extra mile to assist my parents' enquiries, and even got the Samsung staff to help with the data transfer to save us from the hassle.

Went on a weekday so the waiting time is considerably shorter but be prepared to spend a few hours on a weekend.
