They didn't leave a voice mail and it rings busy when I try to call back.
I use my phone for business and hate this type of call.

It's a call center for American Express

called me today. didn't pick up. have had them call me more than once

Called me at 2:36 PM Atlantic (Canadian) time on January 4, 2008. Claimed to be part of some organization that sends out Neilsen-style booklets for people to record their radio listening habits, in order to help determine radio ratings.

Got 2 calls on cell phone (23 January 2008) but no messages, keeps hanging up if not answered.

since i switched to aliant from eastlink i started getting these calls, i never answer a number i don't know but when my machine picks up the people on the other end just keep saying hello hello . where do they get my number when it's unlisted?!?!?!
