Hi,
I like it, but some of the strategies won't work in this country. If you opt for call back (if it's even offered!), you almost never get a call back. A number of menus have a button other than 0 to get to an operator. If you press it, you may get pushed back to the beginning of the menu. You have wait, and then find out to get a person, it's number 5 or number 8.
We also don't have music on some lines; instead we get commercials for the company. I miss the music, as irritating as it can be. Too many commericials and I start screaming. As for keeping the alleged human who answers on the phone, I keep them on way longer than 3 minutes. I take at least that long to complain about the menu, the lack of humanity, etc., etc. And in the interest of killing time, I've thought of creating a few commericials about how wonderful I am and all my achievements that I can read to them, too, read very slowly...
