I found that all emergency numbers did not include a foreign service hotline they lauched few(2, I think) year ago.
That is a toll free hotline: 0800-024-111, which literally solve most of your problems. I got a drivers' license problem and did not know where to go. This hotline solve it. Plus, I heard lots of friends using this hotline as a communication tool to taxi driver.
Most important of all, it is FREE, and 24-hour services. You can call from home, or even mobile.
Hope more and more people find it helpful.
