Got a call a girl asked me if there was a Joe here then giggled and hung up but her voice sounded like she was in her early 30s.

Got a call, didn't answer called back the number later and no answer and line went dead..

Weird, just block your number and call back and say something annoying. If you get mad, then they win.
