I called 1800 9742 273 but they either hang up when I raised my voice (when they cannot resolve my problems) or they hang up immediately when the phone calls went through.

My problem:
Cannot LOG IN my small business account on my desk top suddenly. I did not change password but they kept asking me to key in correct password. Yahoo AP on the otherhand is working well as I did not log out. What is going on....... can someone help me ?????? A real person who can just call me +65 9727***1
