This number calls and does not ever leave a message....

its a bill collector. I kept getting calls from the same number until I finally told them they had the wrong number lol

Keeps calling my cell. Wont leave a message. Will not answer unrecognized numbers

It sure would be nice if this number would quit calling me up, cause for one I'm on a Do Not Call List and if these calls keep up I'm getting my Lawyer in the picture of taking care of whoever is calling!

Before spending big bucks on a lawyer, you need to know one thing, who is calling you and where they are located.  Then at that point you can send them a certified, return receipt letter telling them to stop calling you.  When they don't stop, then you get the lawyer to sue them.
