Who called from 4254069559

Caller id read "4254069559", so I let it roll to the answering machine - no message left.

They called again this evening, caller id read "4254069559", so I let it roll to the answering machine - no message left.

Just called my home but I did not answer.  Caller ID only read "425-406-9559"........

Called a third time tonight, with the same caller id, "4254069559".  Someone hasn't gotten the message; I don't open my front door to strangers, and I don't take telephone calls from them either.
