They called me but would not leave a message.

same thing..
I dont pick up anythign 1800 or 1877 and if they dont leave messages, I wont ever know who it is..
annoying.
I just got a call too

I got the call around the same time as well. Did not pick up and no message was left. I have had debt collectors calling me looking for someone who is not at my number so I am assuming its a collector.

They call at least once a day.  Getting pretty tired of it.  No message left.

missed calls
