Waiting time is way too long to get in touch with the customer service. Same waiting time between services, the line cut once for no reason. The second time, I was given a phone number which is no longer in use, and transferred to that same number (I've had to queue up again from there). I am now in the queue for the 3rd time and have been waiting for another 10 minutes, which I suspect will double or triple if it's like the previous two times. The fact that this has to be dealt with on work days and working hours only (Mon-Fri 9am-5pm) makes it even less convenient, for the majority of the population, as you can't even consider resolving your issue quickly over your lunch break because of that queuing time. I have also attempted email queries a few times - I am still waiting for an answer on one of my queries from a couple of months ago, and had to wait a few weeks for a previous query, only to receive a pre-saved template answer which did not help resolving my issue.
