Capital Management Services, LP Harrassing my parents neighbors Buffalo, New York

These people have been calling me numerous times a day for a debt that I not yet paid.  At this time, I cannot pay it and I know what my rights are regarding that.  I no longer answer the phone, so they have resorted to calling my parent's home and since they do not respond to the call, they have now resorted to calling my parent's neighbor telling them that my phone has been disconnected and they are trying to get information from neighbor about me.  I am very angry as these people have no right to discuss my personal financial business with anyone other than myself.  I do not feel they have the right to call my parent's neighbors and give them this information either.  The neighbor's called me today and gave me the man's name-Joseph Delligrino from Captial Management ID#69872110, phone number 1-800-504-2140.  Since when are these people allowed to harrass your neighbor's, especially when they are lying to them about my phone being disconnected?
