They describe their company as  a Credit Management company (i.e. debt collectors)

Have repeatedly expressed - "do not call here anymore"  and on the "Do Not Call" registry, but the harassment calling continues!! These unidentified people are under the impression they can continue to 'attempt to collect dept' regardless of what number they call.

A nice lady said "Thank you for calling Credit Management Services" when I called the number back.  I told her my name and that wasn't the person she was looking for.  She said she'd remove my number.

they did not leave a message

This person calls my cell phone and either leaves no message or leave a threatening message for another person. I have left her messages on her call back number telling her she has the wrong number and the wrong person, but she continues to call my cell phone harassing me. Someone needs to make this stop!
