They called my cell phone and left me a message that they would be "delivering documents at my place of employment, or at my residence within the next few days".  I have tried to call them back, and they leave you on hold for several minutes before putting some poor non-english speaking person on the phone.  I cannot figure out who the debt is from, and have asked repeatedly for them to send me proof of the debt but they do not understand enough English to figure out what I am saying.  I have blocked them from my cell phone...I LOVE 'STRAIGHT TO VOICEMAIL'!!!!!
