assholes

No message, just continuing calls, nobody on phone when answered.

Automated message asking me to hold for an important message. I always hang up. Nothing is more rude than an unknown number wasting my cellphone minutes and trying to put me on hold when their system dials. If it's really important, a live human can call me back, otherwise they can get bent.

This number calls at least weekly with 7-10 calls in rapid succession, system hangs up before reaching voicemail. I usually pick up eventually and tell them to remove me from their database. They say they will, but obviously they don't. If I call the number back it's listed as out of service, so they're using it as a cover for the real numbers they're calling from.
