Several calls received.  Nobody on the other end, then a hang up/disconnect after a few seconds.

Someone from 603-574-4804 on a daily basis.  Never leaves a message.  Who is it?

Got these calls myself and called back to find out that it was Discover Card Marketing.
I have an account with these guys and I assume they value my business so I contacted
them via online chat and asked them how to opt-out of their marketing calls.  Gave them
my account information (secure online chat) and they said that they took care of it and
I should get no more calls starting in 72 hours plus the time for current offers to work
their way through the system.  We'll see...

These people call me everyday and a recording asks for someone I never heard of. Usually their # doesnt show on my caller ID but today it showed with "unknown" as name. I called it back and they answered mearly hello. I said I just recd a call from this # looking for someone I never heard of. They said quickly "sorry 'bout that" and hung up on me immediately. Almost sounded like a kid. I tried to call it again and it wont ring through.

Relentless. Seems to get similar calls from a Campton, NH and an Alstead, NH number as well

Called my phone number and hung up, have call waiting, left no message.
