My company's employee insurance provider is AIA. It is an extreme nightmare whenever I need to call the hotline number 62488350. Inconsistent information provided by different agents and some of them are utterly rude. Can't even rely on them to send a copy of Letter of Guarantee for hospital admission properly.

The service sucks to the maximum. They don't deserve a single star. Luckily I only need to deal with AIA regarding the company insurance, I can't imagine the horror if I ever buy my own personal insurance from them. Better stay away from AIA.
