no caller ID..hangs up when I answer

I have just recently been getting calls from this number.  They call several times a week.  Since I have no idea who it is, I do not answer.  They never leave a message.

this number called my daughter refused to give her a name and leave a message even after she told them that i didnt live there she called me in panic mode and i am very upset my ten year old told me that this man asked her my whereabouts if he could have my phone number and what kind of car i drove insisting that it was important that he find me and speak with me.,  She immediatly called me and i tried to call this number back from my and a friends phone and recieved no answer.  I am disturbed by the fact that an adult would persistantly ask a child so many intrusive questions.  I did a little bit of research on this number which is how i got to this page and I dont know of anything or anyone in LYTLE< TEXAS.  But if it is a legitamate business then why is the number unlisted and why would any legitamate business harass a small child by probing them with questionjs.. If this number persist i will prosecute to the fullest.

press 1 for English machine says someone will be with you shortly then a recording says your call is important to us please hold. Then a guy gets on the phone says what can I help you with today, I told him I don't know you called me and he hung up. I search the number and it says it is unlisted, a legitimate business with an unlisted number.

press 1 for english   tks someone will be right with you.
