Collectors. They left a message on my machine. The guy acts as if he knows me personally.

Called several time to leave a message on my cell phone. The message is to Jennifer asking her to return his call to the 720 number. There is no Jennifer using my cell phone.  I don't respond.

Caller asks if I know a certain person who lives across the street from me. Callers name reported as Micheal Gilchrist.

Guy calls, very friendly, asking for one of my adult children who moved away several years ago.  Asks for a new phone # which I of course refuse to give him.  He basically tells me he'll keep calling until I give him a number.  WTF!

A woman has called twice asking for a specific person.  The first time I told her that she had the wrong number.  She pressed me for more info, which I could not/would not give her.  The second time she called, I recognized the number on caller ID.  I asked her the address of the person she was looking for and it did not match mine.  At that point I told her not to call my house again, since it was obviously a mistake.
