Google Adwords in Taiwan Sucks

After using Google Adwords more than half a year, I reach a conclusion that it sucks comparing to the size of Google.

1. the email response from the customer service requires one working day. Moreover, they can do nothing but forward the complaints about the pesky hassles to those unknown related departments.
2. Taking weekends off, no available 0800 special line for paid clients (Yes, paid ones cannot enjoy the special line because it's for the possible would-bes.), failing to answer questions immediately while presuming clients to get served only if he or she is qualified to type and email, aren't Google aware most managers of traditional companies are impatient with slow internet support?
3. Google seems to be so self-confident as the leader of the keyword advertisement business in Taiwan that they can delay invoices by several weeks later than their competitors even after receiving the payments.
4. prepay billing by credit card is unscheduled (at least nobody knows the timetable.) while no invoices are provided in Taiwan if postpay billing by credit card is chosen.

It goes without saying Google is such an international giant. However, it is also funny why they always react like retarded dinosaurs and treat as trifles those crucial operations which play a vital role in reality on user experiences as well as evaluations?
