They call and don't leave a message. Tired of this stuff.

They keep calling me, too and don't leave a message. Must be a telemarketer or solicitor. I don't take any calls I don't recognize.

This number keeps calling me and not leaving a message. What is going on? If this is a telemarketer or solicitor, stop calling me immediately, otherwise leave a message and show yourself.

Keeps calling! When I call it back it will not tell me  what company it is. It just tells me what time to call back.
