I agree with cigarman, except I would say more like 25/75. I've pretty much stopped using 1-800-WECARE2 the last couple of years; when I have an issue with CO, I write a letter, and when I run into a difficulty that I need help with, I call the "Platinum line." (Even if it's not a special line, they are almost invariably helpful to me.)
I've always wondered whatever happened to 1-800-WECARE1; I tried it and got that irritating "siren" followed by "We're sorry. You have reached a number that cannot be reached from your calling area." Anyone on the East Coast want to give it a try?
