Just a silent or hangup call.

These people should be shut down because they use automated machines and do not allow you to tell them to stop.  Their mailbox is "full."

Call on caller ID called it back, got a bill for a call to Ottawahull, On

i didn't answer the call.  It appeared they left a message, but when
I went to listen to my messages, there was nothing.  just a blank.

Have no idea who this is.  They leave no messages.  Calls at different times of the day.  Would like for them to stop.  We do not answer, but the phone ringing with unwanted calls is annoying.

Stop calling me!
