Callls at least once daily.  Leaves no message.  STOP it!

We get at least 3-4 calls starting at 8am then maybe 2 more hours get another. They keep asking about where our daugther is, and I tell them the same, I do not know. This morning the man called me a liar and flat out told me I did. I have had it with the rude calls from these people and want it to stop.
