They keep calling my house everyday and when I pick up (to tell them to take me off the list!) nobody answers and eventually they hang up.

Calling my work help desk number-they don't even know they are talking to a voice mail-keep saying hello, hello.  Well, duh!  Very annoying and don't speaka da ingles very well.

Call from Saint Cloud, MN. They call at least three times a day! if it is a bill collector, they are calling the wrong person, as I have no outstanding bills. When I answer they transfer me to a automated voice and then no one is there. REALLY ANNOYING> my number in on the do not call list, so I have no idea how they got it.

I get daily hang ups at my work

Collectors using an "autodial" system; thus talking to your voicemail (when the liver person comes on, that person only knows some kind of connection was made....ie the phone was answered, not who - or more aptly- what answered it)
